Hi , Great post , thank a lot ,
i am working on this post now a days ,
and i followed every step you described i.e : changing wsdl , updating class by adding attributes
and page is working fine . thanks .

My question is regarding some method you defined createobejct() , creatfields etc ,
you said "this will need to be done in your Visualforce controller via a timed refresh or via a scheduled job." how to accomplish that

cause when i m saving them in a apex class I am getting following error :

-> Save error: Initial expression is of incorrect type, expected: MetadataService.Metadata
at line
->MetadataService.AsyncResult[] results = service.create(new List<MetadataService.Metadata> { customObject });

Can you give a simple example of calling createobject() method to insert new object

Thanks in advance

Hi Andy,

First of all - thank you for such a great resource on using the metadata api. I have tried playing around with it and got some satisfying results. Just wanted to ask if you managed to write any test cases for the classes? I have been struggling to do so and any help will be hugely appreciated.

Dear Andrew,
Thanks again for stepping forward to help!

My use case is to retrieve the list of all email alerts in my org with their name, description, sender-address, recipients, & CC'ed recipients. For this I have come up with the below code which I execute from the anonymous exec in dev console.

MetadataService.MetadataPort service = MetadataService.createService();

List<MetadataService.ListMetadataQuery> queries = new List<MetadataService.ListMetadataQuery>();
MetadataService.ListMetadataQuery queryEmailAlert = new MetadataService.ListMetadataQuery();
queryEmailAlert.type_x = 'WorkflowAlert';
queries.add(queryEmailAlert);

//get metadatalist
MetadataService.FileProperties[] properties = service.ListMetaData(queries,30);
for(MetadataService.FileProperties emailalert:properties){
        system.debug('Email Alert Name:::'+emailalert.fullname);

       //read metadata
       MetadataService.Metadata[] mdInfo = service.readMetadata('WorkflowAlert',new String[]{emailalert.fullname}).records;
        for(MetadataService.Metadata md:mdInfo){
            MetadataService.WorkflowAlert alert = (MetadataService.WorkflowAlert)md;
            system.debug('description:::'+alert.description);
            system.debug('From:::'+alert.senderAddress);
        }
}

But the execution stops with the error:

 "incompatible types since an instance of MetadataService.Metadata is never an instance of MetadataService.WorkflowAlert"

I believe it doesn't allow Metadata to be Typecast to WorkflowAlert. But I am not sure if the results can be achieved without doing that.
Can you please help letting me know where I am going wrong here?
Greatly appreciate your help! Many Thanks!

Note:
Since the class generated by the MetadataAPI wsdl exceeds my Apex Limit, I have cut it short to contain only what is required to achieve the required use case. Below is my short version of the MetadataService class used here for additional info, in case you like to have a look.

There is a new CRUD call in Spring '14 / API 30 named "readMetadata" (http://www.salesforce.com/us/developer/docs/api_meta/Content/meta_readMetadata.htm).

I expect this is an implementation error but since it's a new call I thought my challenge was worth reporting.

I think in my instance the SFDC parser was failing to recognize the response as the CustomField class extending Metadata.

Error message: Web service callout failed: Unable to parse callout response. Apex type not found for element externalId

Here's the raw soap response up until the point of failure
'''
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns="http://soap.sforce.com/2006/04/metadata" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

And the apex classes for the parsing
'''

public SFDC_API_MetaData.ReadResult result;
private String[] result_type_info = new String[]{'result','http://soap.sforce.com/2006/04/metadata','ReadResult','1','1','false'};

[...]
}
'''

Adding "public boolean externalId;" to the Metadata class results in the next field being reported as missing. I think the instruction to create CustomField instances is in the "xsi:type='CustomField'" attribute of the tag, which uses a different namespace (which you can see I've been fiddling with).

Given the amount of Apex code that this creates in the respective Orgs, it would be interesting to create 1 org that exposes these as Apex REST services and then anyone call those Apex REST services using the session Id from the respective orgs. You can either use the Ajax proxy to make the call using JS form a VF/Custom button or use Apex HTTP callouts to make these calls.

Essentially make this MDAPI-aaS so that any improvements you do to this single org can be automatically available to everyone consuming.

i am using apex-mdapi .i invoked the function

MetadataService.ReadFlowResult c = (MetadataService.ReadFlowResult) service.readMetaData('Flow', new List{'Calculator','SAMPLE_Lead_Convert_Flow'});

I am using your Metadata API wrapper class to get information about our org. I want to retrieve all custom fields present in my org. I am using listMetadata() method which returns list of components. Below is my code:

MetadataService.MetadataPort service = createService();            
        List<MetadataService.ListMetadataQuery> queries = new List<MetadataService.ListMetadataQuery>();       
        MetadataService.ListMetadataQuery queryLayout = new MetadataService.ListMetadataQuery();
        //queryLayout.folder = MetaDataFolder;
        queryLayout.type_x ='CustomField';
        queries.add(queryLayout);      
        MetadataService.FileProperties[] fileProperties; 
        try{    
         fileProperties= service.listMetadata(queries, 29); //here 29 is api version
        }catch(exception e){
            ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.Info,e.getMessage()));
        }

I am get exception as "IO Exception: Exceeded max size limit of 3000000". I know that number of custom fields present in my org is to much and the response that I am getting exceeding the allowed limit of 3MB. I want to list all custom fields present in my org. Same exception is coming when I am retrieving few other metadata(like all profile). Above mentioned code works fine in my developer org but in sandbox, its not working as number of metadata components is too much in my sandbox.

I tried retrieving the components using Workbench which also uses metadata api. Workbench retrieved all components successfully. So there will be some mechanism in metadata API through which I can retrieve large number of components. I saw few post where people says to retrieve info in different chunks by splitting single request in 2 or 3 different request. But in my case, I am not able to split my request as I want all custom fields.

Can you guide me on how I can resolve this issue ?

Hi,

I want to list metadata about Approval Process, when I changed the API version to 30 in "MetadataRetrieveController" class then it shows me "ApprovalProcess" in "Metadata Type" but when as I select this value then getting error "Cannot use: ApprovalProcess in this version faultcode=sf:INVALID_TYPE faultactor=".

Can you please help me to fix this issue.

Thanks in Advance.

Hi Andrew,

Your API is pretty good. I have a problem on getting ListView for objects.

Your API tells us how to create and delete listviews. I want to know how to get (search) listviews for object.
Can you please provide some code to get the List Views for each object?

As per my requirement I have to add components to Home Page Layout through Apex, and my client has suggested to use Metadata API. I found two wrapper classes “HomePageLayout” and “HomePageComponent”,, but I am not able to add components to HomePageLayout . I am stuck in this big time. Could you help me please

Hi ,
I was working on assigning Picklist values to record type (Updating Record Type )and i discovered a huge issue
May be you can help me out here

1 . Here is the code for creating a Record type
Object : Lead
New Record Type name : Second Record Type
business Process= first lead process
Picklist Field : dependent picklist
Existing Picklist values in this Picklist - Dependent 0 , Dependent 1 , Dependent 2 , Dependent 3

Picklist values to be assigned in this record type :  Dependent 0, Dependent 1 , Dependent 2

Public static void InserRecordtype()
    {
        MetadataService.MetadataPort service = createService(); 
        MetadataService.RecordType rt = new MetadataService.RecordType();
            rt.fullName='lead.second_Record_Type';
            rt.label='Second Record Type';
            rt.active= true;
            rt.businessProcess= 'first lead process';
        
        MetadataService.RecordTypePicklistValue mrt = new MetadataService.RecordTypePicklistValue ();
            mrt.picklist = 'dependent_picklist__c';
                metadataservice.PicklistValue two = new metadataservice.PicklistValue();
                    two.fullName= 'Dependent 1';
                    two.default_x=false ;
                metadataservice.PicklistValue three = new metadataservice.PicklistValue();
                    three.fullName= 'Dependent 0';
                    three.default_x=false ; 
                    
                metadataservice.PicklistValue four = new metadataservice.PicklistValue();
                    four.fullName= 'Dependent 2';
                    four.default_x=false ;       
                
          mrt.values = new list<metadataservice.PicklistValue> {two,three,four} ;
          
        rt.picklistValues = new list <MetadataService.RecordTypePicklistValue>{mrt};
        
      MetadataService.AsyncResult[] results = service.create (new List<MetadataService.Metadata> { rt });
    }

---- works perfectly , new Record type created , and picklist values assigned for field ---------------

2 . Now .
if I want to add new values in Assigned Picklist Values at above record type
New Picklist value to be added : Dependent 3
so here is the code for updating record type

 

Public static void UpdateRecordtype()
    {
        MetadataService.MetadataPort service = createService(); 
        MetadataService.RecordType rt = new MetadataService.RecordType();
        rt.fullName='lead.second_Record_Type';
        rt.label='Second Record Type';
        rt.active= true;
        rt.businessProcess= 'first lead process';
        
        MetadataService.RecordTypePicklistValue mrt = new MetadataService.RecordTypePicklistValue ();
        mrt.picklist = 'dependent_picklist__c';
            metadataservice.PicklistValue five = new metadataservice.PicklistValue();
                five.fullName= 'Dependent 3';
                five.default_x=false ;
           
          mrt.values = new list<metadataservice.PicklistValue> {five} ;
          
        rt.picklistValues = new list <MetadataService.RecordTypePicklistValue>{mrt};
        
        
        
         MetadataService.UpdateMetadata ut = new MetadataService.UpdateMetadata();
        ut.currentName='lead.second_Record_Type';
        ut.metadata= rt;
       MetadataService.AsyncResult[] results = service.updateMetadata(new List<MetadataService.updateMetadata> {ut});
    
    }

3- Ideally in a perfect word : now assigned values should be : Dependent 0 , Dependent 1 , Dependent 2 , Dependent 3

.............................BUT ........................
---> Now assigned value contain only : Dependent 3 (i.e it removes all existing values )

So my question is : is there any method to get existing assigned picklist values for any record type
in my case Dependent 0 , Dependent 1 , Dependent 2 . before inserting new values
If i pass
Object : lead
Record type name : Second record Type
Picklist Field name : dependent picklist

In Describe Metadata or any other method ???

or , any method by which we can keep the existing values and add new picklist values without removing old one ??

Hi , Great post , thank a lot ,
i am working on this ,

Hi Andrew,

I am facing below exception when I log in as non admins. It works well for Sysadmin.
System.CalloutException: Web service callout failed: WebService returned a SOAP Fault: INSUFFICIENT_ACCESS: use of the Metadata API requires a user with the ModifyAllData permission.

Apex runs in system mode how does Metadata API taking the permission of the user. Can you please help me in understanding this.

Thank you in advance.

I have been implementing a solution with you library (It is awesome thanks for all the work). I had my test working and creating visualforce pages successfully 2 days ago, now I am getting the exception message in the title.
I have tried googling this but could not find any information. Have you experienced this before?

Hi andrew fawcett,

Field accepted but Layout name not accepted(Fullname Error).My object name like below

String objectname='rajesh__'+objectname+'__c';//In debug like:rajesh__Test__c

I try to below ways:

1)MetadataService.Layout layout =
(MetadataService.Layout) service.readMetadata('Layout',
new String[] {'rajesh__+objectname__c-rajesh__+objectname Layout'}).getRecords()[0];//here problem
2)MetadataService.Layout layout =
(MetadataService.Layout) service.readMetadata('Layout',
new String[] {'rajesh__'+objectname+'c'-'rajesh'+objectname Layout'}).getRecords()[0];//here problem
3)String obj='rajesh__'+objectname+'c';//debug no problem:rajesh__Test__C
String layoutname='rajesh'+objectname;//debug no problem:rajesh__Test
MetadataService.Layout layout =
(MetadataService.Layout) service.readMetadata('Layout',
new String[] {'obj-layoutname Layout'}).getRecords()[0];//here problem

Above 3 ways same error:

Hi Andrew,
I really like the work you've done here - I've been applying it to several different projects. I have a need to programmatically modify the sharing on list views, i've been playing around with this but I haven't been able to achieve the results I'm looking for. When I pass a list to the updateMetadata method, the pieces I have declared update but everything else is set to erased; such as the fields, filters, etc. Second, I noticed that updating some lists I need to designate the listView.filterScope or an error returns "System.CalloutException: Web service callout failed: WebService returned a SOAP Fault: '' is not a valid value for the enum 'FilterScope' faultcode=soapenv:Client faultactor=", which isn't a huge problem but I would have to set that value to 'Everyone' that may overwrite some lists settings.

In a perfect world I'd like to run this process:

1. Query all listViews created by a specific user/role
2. Change the sharing to a public group
3. Update

I've attached the code I've found to work best so far, and to simplify i'm only looking at a single list - ideally I would run it in bulk. If you have any pointers please let me know, maybe i'm using this completely wrong.

'''

public void listViewShare(string lvName){
    MetadataService.ListView listView = new MetadataService.ListView();
    listView.fullName = 'contact.'+lvName;
    listView.filterScope = 'Everything';
    listView.sharedTo = new MetadataService.sharedTo();
    listView.sharedTo.groups = new list<String>{ 'Territory_Central' };

    List<MetadataService.UpdateMetadata> updateMetadataList = new List<MetadataService.UpdateMetadata>();   
    updateMetadataList.add(new MetadataService.UpdateMetadata());
    updateMetadataList[0].currentName = 'contact.'+lvName;
    updateMetadataList[0].metadata = listView;

    MetadataService.AsyncResult[] results = service.updateMetadata(updateMetadataList);

line 246:I called addFieldToLayout()

It took me quite a time to figure picklist , controlling, dependent etc so . i though it would be helpful addition on your work

Here is the example for Creating picklist field , with controlling field , and controlling field values

  public static void createPicklistField()
    {
        MetadataService.MetadataPort service = createService();     
        MetadataService.CustomField customField = new MetadataService.CustomField();
            customField.fullName = 'lead.dependent_picklist__c';
            customField.label = 'Dependent Picklist';
            customField.type_x = 'Picklist';
            
        
        metadataservice.Picklist pt = new metadataservice.Picklist(); // creat picklist metadata
            pt.sorted= false;
            pt.controllingField = 'Controlling_Picklist__c'; // Define controlling field only name . not object name, only if you are creating Dependent field , else dont include line : if field dependency doesnot exist , it will create new one
        
        metadataservice.PicklistValue one = new metadataservice.PicklistValue(); // create picklist values metadata
            one.fullName= 'Dependent 0';
            one.default_x=false ;
            one.controllingFieldValues = new list <string> {'Control Odd number'};  // assign controlling field values
           
        metadataservice.PicklistValue two = new metadataservice.PicklistValue();
            two.fullName= 'Dependent 1';
            two.default_x=false ;
            two.controllingFieldValues = new list <string> {'Control Odd number','Control Even number'}; // assign controlling field values
            
        pt.picklistValues = new list<metadataservice.PicklistValue>{one,two}; // assign picklist values
            customField.picklist = pt ;                                       // assign Picklist
        MetadataService.AsyncResult[] results = service.create (new List<MetadataService.Metadata> { customField });
      
    } 

and here is the code to update picklist field

 

public static void UpdatePicklistField()
    {
         MetadataService.MetadataPort service = createService();
         MetadataService.CustomField customField = new MetadataService.CustomField(); 
            customField.fullName = 'lead.dependent_picklist__c';
            customField.label = 'Dependent Picklist';
            customField.type_x = 'Picklist'; 
            
        metadataservice.Picklist pt = new metadataservice.Picklist();
            pt.sorted= false;
            pt.controllingField= 'Controlling_Picklist__c'; //***** name of controlling field . if picklist has contrlloing field , this must be asssigned . else field dependency will be deleted
            
                metadataservice.PicklistValue first_dependent = new metadataservice.PicklistValue();
                 first_dependent.fullName= 'Dependent 2'; 
                 first_dependent.default_x=false ;
                 first_dependent.controllingFieldValues = new list <string>{'Control Even number'};  // list of names of controlling field Picklist value . dont put this line , if you dont want any controlling picklist value
           pt.picklistValues = new list<metadataservice.PicklistValue>{first_dependent};
         customField.picklist = pt ;

    }

I Want to Create a Button But I have got this exception "Save error: Initial expression is of incorrect type, expected: MetadataService.Metadata" . How Can i Resolve this?

Hi. I'm trying to update Layout:

    MetadataService.MetadataPort service = new MetadataService.MetadataPort();
    service.SessionHeader = new MetadataService.SessionHeader_element();
    service.SessionHeader.sessionId = sessionId;
    service.endpoint_x = endpoint;

    MetadataService.Layout layout = 
        (MetadataService.Layout)service.readMetadata('Layout', 
            new String[] { 'CaAwsCloudTrailEvent__c-AWS CloudTrail Event Layout' }).getRecords()[0];

    System.debug(layout.fullName);

    handleSaveResults(
        service.updateMetadata(
            new MetadataService.Metadata[] { layout })[0]);        

    System.debug('DONE');

but getting error "Required field is missing: fullName", because retrieved field fullName is null. It is possible update MP page layout through metadata api? Thank you.

I have been trying to hit the metadata api by making a callout from Salesforce.com. I was successful in retrieving Validation rules/ List Views et al using JSZip and the metadata controller for the system Administrator.

However, when the User who has been "API enabled" but not a System Admin access it , he gets logged out when clicks on a button that internally makes a callout. Although, I am not making use of the exact same code, I am essentially trying to do the same thing. May be I am just missing something here, but I would be glad if you could replicate it? Am I missing something at the Profile level?

Winning Record A ("Customer DM" recordtype) has sharing granted to a set of 5 roles
Losing Record B ("Customer CRM" recordtype) has sharing granted to a Role "Director de CSO" and a Public Group "CSO Back Office" as well and these two sharing settings are not present on Record A.
Upon Merge, we should assign the Sharing Settings on Losing Record B to the Winning Record A.
This way all users who had access to Record B, will have access on Merged Record A.

How can we achieve this, can we handle this case by providing extension to default feature.

       MetadataService.MetadataPort service = createService();

      List<MetadataService.Metadata> myCustomlayoutList = new List<MetadataService.Metadata>();
       // Read the Layout
    MetadataService.Layout layout =
    (MetadataService.Layout) service.readMetadata('Layout',
    new String[] { 'rajesh__+ strFieldName+__c-strFieldName Layout' }).getRecords()[0];

    // Here add your field by finding or adding the layout section and columns etc…
   MetadataService.LayoutItem LayoutItem = new MetadataService.LayoutItem();
    LayoutItem.field = 'rajesh__'+ strFieldName+'__c.'+'rajesh__'+Field2+'__c';
    // This code assumes the first section, first column of the layout
 layout.layoutSections[0]. layoutColumns[0].layoutItems.add(LayoutItem);

    // Update the Layout
    handleSaveResults(

Hi Andrew,

Greetings and much adulation for your work and your passion for APIs.

I have been following your GIt and trying to build a component which will allow taking Org backup of metadata. I have been able to do this for single metadata type but as per documentation "The queries array can contain up to three ListMetadataQuery queries for each call. "

This limitation if I understand correctly will not allow retrieving more than 3 metadata types per call.

So for this we will have to make successive calls and retrieve metadata but that will be in separate files and separate package.xml.

If IDE and ANT are also based on same API then how do they handle this kind of requests/limitation. Both of them provide single files for zip and packaga.xml.

Is this possible in APEX? to have the single file single package behavior as well?

Could it be like we have to use tooling and metadata api together at the same time to achieve this?

Thanks again for your time and guidance.

Is there a way to insert the record types on an object using metadata api.

In a brand new org, all I did was to deploy this package and add a remove site as the self: in my case: https://c.na15.visual.force.com. I am able move around in all the other pages but when I visit metadatadata. I get the following error, what am I missing?

Visualforce Page: /apex/metadatadata

caused by: System.CalloutException: Web service callout failed: WebService returned a SOAP Fault: INVALID_TYPE: Unknown type: faultcode=sf:INVALID_TYPE faultactor=

Error is in expression '{!constructResponse}' in component apex:page in page metadatadata

Class.MetadataService.MetadataPort.listMetadata: line 1506, column 1
Class.MetadataDataController.constructResponse: line 58, column 1

Currently if the developer does not setup the Remote Site setting instead of the system exception informing them to do so, the browsemetadata demo just shows a blank tree with no error.

Hi, Thank you for a such a great post.

Facing an issue At this point

MetadataService.SaveResult [] results =
service.createMetadata(
new MetadataService.Metadata[] { customObject });

The Error is : Compile Error: Initial expression is of incorrect type, expected: MetadataService.Metadata

This is how i declared Sobject type
MetadataService.CustomObject customObject = new MetadataService.CustomObject();
Kindly help me resolve this.

Hi Andy, I'm getting the following error when deploying to my dev org (I used your button/ heroku app):

classes/MetadataServiceTest.cls(76,9):Method does not exist or incorrect signature: Test.setMock(Type, MetadataServiceTest.WebServiceMockImpl)

Hi , i been working on creating picklist , updating and assign to controlling field
and i came across an issues . that might interest you .

so ..

1. I can Create new picklist field via this method :

  public static void createPicklistField()
{
    MetadataService.MetadataPort service = createService();     
    MetadataService.CustomField customField = new MetadataService.CustomField();
    customField.fullName = 'lead.picklist__c';
    customField.label = 'picklist';
    customField.type_x = 'Picklist';

    metadataservice.Picklist pt = new metadataservice.Picklist();
    pt.sorted= false;

    metadataservice.PicklistValue one = new metadataservice.PicklistValue();
    one.fullName= 'first'; 
    one.default_x=false ;

    pt.picklistValues = new list<metadataservice.PicklistValue>{one};
    customField.picklist = pt ;
    MetadataService.AsyncResult[] results = service.create (new List<MetadataService.Metadata> { customField });


}

2. I can update / add new values via :

public static void UpdatePicklistField()
{
    MetadataService.MetadataPort service = createService();     
    MetadataService.CustomField customField = new MetadataService.CustomField();
    customField.fullName = 'lead.picklist__c';
    customField.label = 'picklist';
    customField.type_x = 'Picklist';


    metadataservice.Picklist pt = new metadataservice.Picklist();
    pt.sorted= false;
      metadataservice.PicklistValue two = new metadataservice.PicklistValue();
        two.fullName= 'second';
        two.default_x=false ;

        metadataservice.PicklistValue three = new metadataservice.PicklistValue();
        three.fullName= 'third';
        three.default_x=false ;
    pt.picklistValues = new list<metadataservice.PicklistValue>{two,three};
    customField.picklist = pt ;

    MetadataService.UpdateMetadata ut = new MetadataService.UpdateMetadata();
    ut.currentName='lead.picklist__c';
    ut.metadata= customField;

    MetadataService.AsyncResult[] results = service.updateMetadata(new List<MetadataService.updateMetadata> {ut});


}

1. Now issues arises when i decided to add values in any depend picklist field :
   suppose there is a relation : controlling field : picklist..c : values : first, second, third
   and then dependent picklist : dependent_picklist..c , values : -none-

and now i write code to insert new value: "first_dependent" in dependent picklist

code is saving and running fine

  public static void update_dependent_PicklistField()
{
    MetadataService.MetadataPort service = createService();     
    MetadataService.CustomField customField = new MetadataService.CustomField();
    customField.fullName = 'lead.dependent_picklist__c';
    customField.label = 'dependent_picklist';
    customField.type_x = 'Picklist';

    metadataservice.Picklist pt = new metadataservice.Picklist();
    pt.sorted= false;
    pt.controllingField= 'lead.picklist__c';
       metadataservice.PicklistValue first_dependent = new metadataservice.PicklistValue();
         first_dependent.fullName= 'first_dependent'; 
         first_dependent.default_x=false ;
         first_dependent.controllingFieldValues = new list <string>{'first'};
     pt.picklistValues = new list<metadataservice.PicklistValue>{first_dependent};
     customField.picklist = pt ;


     MetadataService.UpdateMetadata ut = new MetadataService.UpdateMetadata();
    ut.currentName='lead.picklist1__c';
    ut.metadata= customField;
   MetadataService.AsyncResult[] results = service.updateMetadata(new List<MetadataService.updateMetadata> {ut});

}

But it WONT INSERT any value in dependent picklist cause
: its sending update metadata as follows :

Please do let me know your thoughts on this

Hi Andy,
I explored adding OAuth compatibility : getting an OAuth token is easy enough, as well as initialising the InputHttpHeader on the MetadataService.
However, for some reason, WebServiceCallout.invoke insists on using the SessionId in the SessionHeader : have you any reason why ?

Any other idea about making apex-mdapi OAuth-compatible ?

Hi,
I am trying to create "workflow" metadata via the wrapper. I'm having trouble adding the "fullName" attribute to the parent workflow and its child elements

code like this:
((MetadataService.metadata)myWorkflow).fullName = source.subject;
produces this error:
Error: Compile Error: Incompatible types since an instance of MetadataService.Workflow is never an instance of MetadataService.Metadata at line xyz

The attempt to create workflow fails with a similar type error.
MetadataService.AsyncResult[] results = service.create(new List<MetadataService.Metadata> { myWorkflow});

that line fails with an error saying that the method is expecting a metadata object.

Hi Andrew

Hope you are well, and I hope I'm not overstepping the boundaries by asking for some advice here.

Please could you help a guy out? I've been searching everywhere for an answer to this and am going out of my mind.

I can't find a way to programmatically create new ApexTriggers using any of the available Salesforce APIs. The closest I've gotten is using the tooling API, but that always throws an error at me:

http://salesforce.stackexchange.com/questions/14352/how-can-i-create-a-new-apex-trigger-using-the-tooling-api

My question is: how do you people normally create an ApexTrigger programmatically via the APIs. I can handle ApexClasses and Pages, but all my searching returns people asking the same question but getting no answer.

Any help with this would be greatly appreciated :)

Thanks for your time
Tom
