Regisitry file referenced by registerassembly* is missing.

The recent change to include "[Runtime persistent member for DC]" broke something. A newly created web app fails with a "The PersistentEntityStore already has been set." message on logout.
The exception is triggered in the call to XafTypesInfo.SetPersistentEntityStore in line 52 of Xpand/Xpand.ExpressApp/Xpand.ExpressApp/SystemModule/XpandSystemModule.cs.

I think that the problem is the modification of the condition in line 51.

Hi,
I see latest 17.2 release of expand version is 17.2.7.4.
Is expand 17.2.7.4 compatible with any XAF 17.2.X.X ? (I mean 17.2.8 and later)
Regards.

Hi,

I need to disable Edit Connection and Rename button of dashboard design button based on the type of the data source selected in the relative combo (see the attached image).

Please can you indicate me what is the correct approach to implement this behavior?

Thanks,

Davide

Hi

I've added MasterDetailWindowsModule into my Application. Here is my Model.xafml:

But I can't see neither expand button, nor nested grids in my app. How should I configure it?

When the WinApplication Designer loads for the first time, it takes about 2 minutes to load. CPU goes to 75% usage. Then you can use it. However, you close it, build the solution again, and then you cannot see the designer anymore. The error that is shown is:

Hi tolis,
How can i fix that issue ?
Devexpress.Xpo.SimpleDataLayer.SuppressReentrancyAndThreadSafeLayer = true,

im using wc module and i cant set it true

Drop down list for an action shows collection properties for current object type. when executed it colelcts all records for chosen collection for ALL selected items in a target list view. Example: show all invoices for selected customers.

When doing the shortcut Ctrl + Shift + Alt + M i get the following error

The 'eXpandDemo.Web' assembly doesn't contain a ModuleBase descendants

Happens when opening the .Web Project. the .Module, .Module.Web is ok.

I have downloaded last snapshoot, than i converted project files with ProjectConverter bundled with DevExpress 10.1, and when i starting to build with buildall32bit.cmd first project eXpand.Utils building without problems but while building next eXpand.Xpo i recive error Compiler CS0234, and so on.
I am not assured that of it a problem, but DevExpress installation path is not default... but it seems like DevExp's assemblies located in gac.

I am sorry for my bad English

say you have A.a and A.b
db1 is a master database the synchs the data from db2 and db3
db2 has updated A.a and db3 updated A.b fields of the same record
so if i mport both db2 and db3 into db1, it will have the most up to date version of the record -
A.a would come from db2 and A.b from db3

I suppose Export and Import should have a configurable option of using AuditTrail.

A faulty reference to XtraGrid in MemberLevelSecurity.Win

Hi,
I'm using Xpand dashboard module in my project.
Following the example providing in this devEx discussion I'm able to show zero in pivot grid in dashboard designer:
https://www.devexpress.com/Support/Center/Question/Details/T465098/dashboard-viewer-how-to-replace-empty-cell-in-dashboard-pivot-grid-with-zero

My issue is that I can't do the same in dashboard viewer. I try to override some Xpand dashboard controller but I do not find the dashboard viewer object. I only find the dashboard definition object.

How can I replace empty cell with zero in Win and Web dashboard viewer?

Thanks,

Davide

In line 140 of Xpand.ExpressApp.ExcelImporter.Controllers.ImportExtension the first sheet is selected for import.

foreach (var dataRow in dataSet.Tables.Cast().First().Rows.Cast()){

must be replaced with

foreach (var dataRow in dataSet.Tables.Cast().First(table => table.TableName == excelImport.SheetName).Rows.Cast()){

although changing the value of the Base Type properly refreshes the Generated code to match the chosen base object - ie person - when i save the assembly, the derived code uses the eXpandCustomObject as the base class.

Also, the Generated Code of a persistent class info is not always reflecting the changes made to the properties.

Create a new solution and run it. Create an assembly with world creator. Close the app, rerun. Try to view your assembly. You get a db-related error.

I assume that out-of-the-box, eXpand VS template uses a MS Access connection. I saw my Solutionq1.mdb created, but not the WorldCreator.mdb one. But there is a "WorldCreator" file with no extentions. I changed the extention to mdb and it was actually an mdb database.

use the linq bridge library

Hi,

I've got a property like this:

private XPDelayedProperty _Photo = new XPDelayedProperty();
[ValueConverter(typeof(ImageValueConverter))]
[Delayed("_Photo")]
public Image Photo
{
get
{
return (Image)_Photo.Value;
}
set
{
_Photo.Value = value;
OnChanged("_Photo");
}
}

which doesn't get serialized properly. Serialization result is -

As far as I understood, I was not alone asking such a question (http://www.expandframework.com/forum/8-discussion/1920-worldcreator-and-xaf-application-server.html , http://www.expandframework.com/forum/8-discussion/5065-application-server-with-worldcreator.html) and it would be great to realize the availability of objects who created with the help of WorldCreator through the Middle-Tier XpandServerApplication.
If I can help in this matter - please let me know. I did a lot of tests and experiments. Maybe for start - it's possible to load WC (example: through creating Win application in app server code started and after - upload/inject dynamically types to the XpandServerApplication exported types) module when ServerApplication is started...

When creating a new Code Template, no code is inserted when the TemplateType is selected

Hi

I need to expand only first level of a hierarchy. But in my app I can expand it to 2nd, 3rd, ... levels. How to disable it? I set EnableMasterViewMode property to False explicitly. But it doesn't help. Also I tried to change EditorTypeName of the nested entity.

<Application>
  <BOModel>
    <Class Name="EstiMate.Module.BusinessObjects.MaterialEstimate" AutoExpandNewRow="True" />
    <Class Name="EstiMate.Module.BusinessObjects.ServiceEstimate" EditorTypeName="Xpand.ExpressApp.Win.ListEditors.GridListEditors.GridView.XpandGridListEditor" DefaultListViewShowFindPanel="True" />
  </BOModel>
  <Views>
    <ListView Id="Estimate_ServiceEstimates_ListView" EditorTypeName="Xpand.ExpressApp.Win.ListEditors.GridListEditors.GridView.XpandGridListEditor">
      <GridViewOptions>
        <OptionsDetail SmartDetailExpandButtonMode="AlwaysEnabled" AllowExpandEmptyDetails="True" EnableMasterViewMode="True" DetailMode="Embedded" />
        <OptionsView ShowDetailButtons="True" />
      </GridViewOptions>
    </ListView>
    <ListView Id="MaterialEstimate_ListView">
      <GridViewOptions>
        <OptionsDetail EnableMasterViewMode="False" />
      </GridViewOptions>
    </ListView>
    <ListView Id="ServiceEstimate_MaterialEstimates_ListView" EditorTypeName="DevExpress.ExpressApp.Win.Editors.GridListEditor" AllowEdit="True" AllowLink="False" AllowUnlink="False">
      <GridViewOptions>
        <OptionsDetail EnableMasterViewMode="False" />
      </GridViewOptions>
    </ListView>
  </Views>
</Application>

It would be nice to have this feature implemented in Xpand

WorldCreator does not properly update the database model, as part of a new module version deployment process.

While i can successfully export an application model, importing it back throws an exception.

Hello Tolis
I cant open Any model

Where persistentMemberInfo.CodeTemplateInfo is null

I can built and run FeatureCenter.Win, but when I switch to FeatureCenter.Web, I can built successfully but after i log in under user admin. The system throw an error: DevExpress.Xpo.Exceptions.PropertyMissingException: 'Property 'Customer' does not exist within type 'FeatureCenter.Module.WorldCreator.ExistentAssemblyMasterDetail.EAMDOrder

test

I'm writing eXpand documentation for Tolis. I was testing the Combine Order Property to see which one of the models was loaded last.

Testing: I have previously created 3 user models. So I open #1 and then navigated to the #2 and then tried to go to #3. But I couldn't because #2 said it needed changes to be saved (when I didn't make any changes).

I'm using dashboard module in my xaf web application.

If I try to access the property DashboardViewer of DashboardViewEditorWeb class I receive an invalid cast exception.

In source code I see that
public ASPxDashboardViewer DashboardViewer { get { return (ASPxDashboardViewer)Control; } }

Is it correct?

Debugging, I see that the private variable ASPxDashboardViewer _asPxDashboardViewer; is correctly populated.
Could the property DashboardViewer be something similar to:
public ASPxDashboardViewer DashboardViewer { get { return _asPxDashboardViewer; } }
?

thanks,

Davide

Hi,
I have created a new Persistent Assembly Info
Typed "TestAssembly" for Name property.
and clicked Validate
And i get this error : error CS0006: 'mscorlib.resources.dll' Medata file could not be found.
Also, if i save it with errors and exit the program, i cant restart program again. Because it compiles assemblies at beginning and throw Compile errors as exception. It should not throw exception when found compile errors or, after throw exception, program continue to start normally.

Akın GÜNEŞ

Hi,

I write this post in reference to http://www.expandframework.com/forum/8-discussion/5254-dashboard-performance-with-large-data-sources.html#11729 .

Please can you inform me when a model rules to modify the query further and on design/runtime mode is done.

Thanks,

Davide

database update throws an exception when a new assembly is created using wolrd creator with new BOs, and the application is not running under vs - deployment issue.

Error when saveing UserModel and the User key property name is not Oid.

When you have a legacy database and you User class has a differente column for the id like MyId, error occurs during saving.

------- Updating model differences:
Error:
Exception occurs while the 'eXpand.ExpressApp.ModelDifference.ModelDifferenceModule' customizes XPDictionary: Object reference not set to an instance of an object.
Update failed

I started of with the eXpand project template, and I get this issues with world creator:

1. I cannot add anything to a persistenclassinfo (Not proeprties, neither attributes). The New actions are invisible.
2. Assemblies are validated ok - no complilation errors - but i get no new assemblies on the next restart. And i am talking about pure simple "MyAssembly" type of example.

I could use a working sample of a workflow instance. preferably in c#

Hi,
I'm not sure about this. But I think that the VS template that comes with eXpand is missing assemblies for the *.Web project to run. After converting the project, I get:

Hi,
I was doing a test on Generating Runtime Members. Everything worked as expected. After I added the members to Detail and List Views on Win, I wanted to copy them to the Web Model with Combine Controllers. However, I couldn't because apparently, you can only combine:

• Application to User/Model
• User/Model to Application
• User/Model to User/Model

However, you cannot do Application to Application. So the questions are:

1. Is this by design?
2. Which model is the best place to generate runtime members?

Thanks,

Carlitos

I get this error when I try to open the Model Editor through the Command Shortcut
Ctrl + Shift + Alt + M

Exception occurs while initializing the 'eXpand.ExpressApp.WorldCreator.Win.WorldCreatorWinModule' module: Exception has been thrown by the target of an invocation.

The .Module, .Module.Win is ok. Just happens with .Win Project

It'll be helpful if you can update the Latest Download link on expandframework.com to point to https://github.com/expand/eXpand/releases and not https://github.com/expand/eXpand/issues.

now works only if modeldifference module is registered else throw updateshema exception

after installation, I can't add the module from toolbox because it's not there and the project wizard also
