box.com invoice example: path of /rest/upload incorrect

There is a duplicate /rest in the path for /rest/upload.

(I am not actually sure if this is an issue or not, but still wondering why that is. It looks a bit uncommon.)

https://github.com/camunda-consulting/code/blob/0d1ebd05825adb65092a5c59375f5e9398378dae/snippets/ecm-integrations/invoice-box/src/main/webapp/forms/upload-new.html#L46

Invoice demo application "missing" DMN files

I am new to all of this technology so forgive me if I have missed something obvious.
Your last update comment said you added missing DMN files to the Showcase -> English -> Invoice application. I assume that I should see actual files in the folder as I see them in the Insurance folder. However, there are none present.
The current Camunda 7.4.0-alpha3-ee bundle that I have installed has what I assume is a pre-loaded example of this application. I am trying to figure out how to use DMN and this seems like a good example to use, but without the DMN table (file) attached, I'm not sure I'm looking at the right thing.
Please help my ignorance because DMN support is critical to my project.
Thank you.

Update rename-technical-ids-plugin

The dev-dependencies of the plugin are quite outdated. More current versions should be used, e.g.:

  "devDependencies": {
    "bpmn-js": "^8.2.0",
    "browserify": "^17.0.0",
    "camunda-modeler-plugin-helpers": "^2.1.0",
    "inherits": "^2.0.4",
    "lodash": "^4.17.20",
    "min-dom": "^1.0.0",
    "diacritics": "^1.3.0",
    "watchify": "^4.0.0"
  }

Custom query - deserializing variables

What is the best way to handle deserializing all types of variables?
The docs

https://docs.camunda.org/manual/7.5/examples/tutorials/custom-queries/#custom-mybatis-queries

for custom queries refer to code that is no longer present and while the new code is alot more concise than what was there previously its still set up to assume simple string variables.

I'd attempted to recreate what the code does to fetch variables by case execution, mapping the variable fields onto VariableInstanceEntity and querying this object via

getTypedValue(true);

However this fails as in TypedValueField when requesting the VariableSerializer it fail as there is no command context

 public static VariableSerializers getSerializers() {
    if (Context.getCommandContext() != null) {
     ....
    } else {
      throw LOG.serializerOutOfContextException();
    }
  }

It would seem more correct to go this way to recreate the variables since I'm not familiar with the db structure for the ACT_RU_VARIABLE table (and it has lots of different value columns) and the deserialization would work well for complex types etc.

The old code would have created the command context I believe, whats the correct way to go about executing custom queries from within a command context as of v7.5?

optimze lincense key doesn't work

I'm trying to use the events-monitoring snippet referenced here https://camunda.com/blog/2020/04/announcing-camunda-optimize-3.0/

into the license file and I still get an invalid license message.

Cannot access camunda rest api from angular

I got the code running in angular 7. It is also able to hit the rest controller I created and deployed in the camunda springboot container.
But I am not able to hit the camunda rest api from my angular app. All running locally.
There is some setting somewhere that to is preventing this. Can you help me
Thank you for your help and support.

springboot-customized-webapps always brings up errors

If I ever use a customized webjar with spring security, Camunda always throw the error:

Caused by: javax.servlet.ServletException: Could not read security filter config file '/securityFilterRules.json': no such resource in servlet context.
	at org.camunda.bpm.spring.boot.starter.webapp.filter.ResourceLoadingSecurityFilter.loadFilterRules(ResourceLoadingSecurityFilter.java:45) ~[camunda-bpm-spring-boot-starter-webapp-core-7.18.0.jar:7.18.0]

Problems with Box.com Invoice Demo on Tomcat

I try to setup the Box.com demo and followed the instructions, but cannot get it to work properly.

Using Camunda BPM 7.8.0 CE (latest available CE I downloaded today).

I created a box.com app (actually, I tried with two: a custom app and a partner app, because I wasn't sure if it makes a difference.) using OAuth2.0 with JWT.

I configured the config.properties and saved the private_key.pem that I got from the box.com app admin interface, then built the camunda-example-invoice-box app with maven, which built the war file just fine, and deployed it. (I tried with both approaches: deploying the war file, and also deploying the exploded folder under the target directory.)

When going into the Camunda Tasklist, I do see the box window, but there are some issues:

the icon b.png is missing
clicking on the "Open Box Folder" doesn't do anything, and I am not sure what the html/target should look like, or if there is a click event handler supposed to be associated with this link. All that happens is that the same Camunda windows re-opens again in a new browser tab. But not box folder in sight.
I noticed that the <a> has on href nor id. Not sure if this is supposed to be like that.

SSO and saving users in Camunda DB.

Hello! Related to Spring Security Camunda
I have a question about SSO. In regards for the case when SSO is working, but for this case, users don't save into Camunda database. After authentication logs show us warning about it.

It's good to save the data into the User database.
How do you think, how can it be implemented?

×
Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Check the render method of GenericForm.

How to use springboot-customized-webapp with gradle?

Not able to autologin

Hi,

I have included the jar file produced by your code in my build path and added authentication filter in web.xml as described by you. But when I try to open http://localhost:8080/camunda/app/tasklist/?auto-login-username=admin then it will redirect me to default login page (http://localhost:8080/camunda/app/tasklist/default/#/login). Did i miss something ?

Move rename-technical-ids-plugin to camunda-modeler-plugins

This plugin supports camunda best practices and is a really helpfull addition to the modeler. Therefore it should be placed side by side with other plugins.

Furthermore it is referenced from the plugins-repo and even its own source code refers to the plugins-repo as its homepage:

[camunda-modeler-plugin-usertask-generatedform-preview] Not working with multiple plugins editing properties provider

Good morning! As on subject, this plugin does not work If I have multiple plugins that work on propertiesProvider module.
I already worked on it on my projects and I have the solution.
Have a look on my MultiDiagram plugin, at this file

In this way, I extended propertiesProvider instead of replacing it with a new CamundaPropertiesProvider, making the plugin scalable.

I cannot find such folder. Any help ?

box-issue : Getting 404 on clicking Upload during Start Process

After I deployed WAR file and tried to start a process from TaskList. I am getting this 404 in POST request.

approve variable is null when checkbox not checked

In the tasklist react example, if you don't check the 'approve' checkbox, its value is not false, but the variable is discarded.

dirty Fix:

Add values['variables']['approved'] = values['variables']['approved'] || { value: false }
to completeTask in
code/snippets/camunda-tasklist-examples/camunda-react-app/src/actions/camunda-rest/task.js

Add a license file to the repo?

Could you perhaps provide a license file for this repository that explains how the code can be reused?

I would like to use one of the showcases processes (this one: https://github.com/camunda/camunda-consulting/tree/master/showcases/bank-account-opening-error-handling) for an academic paper as a simple example for an executable BPMN process. I would depict the process in the paper and then compute a structural code metric for the process. The purpose of the paper is to propose this metric. I would cite Camunda as authors of the process and provide a link to this repository in the paper, of course. Is this ok for you?

Thanks a lot!

Documentation link on the README page is broken

The Documentation link at the very bottom gives 404.

camunda-example-invoice-cmis: Logic issue "The case execution is already in state 'completed'."

Assign Reviewer: > Assign to yourself / demo > click 'Complete'
Review Invoice: > check "Could you clarifiy the invoice" > click 'Complete'

ReadMe of Customize the Camunda Webapps in Spring Boot

Hello,

The ReadMe file of https://github.com/camunda-consulting/code/tree/master/snippets/springboot-customized-webapps is not updated after 7.10 changes with the correct path:

Possibly addionally adjust the contents of springboot-customized-webapp-webjar/src/main/resources/META-INF/resources/app/{tasklist|cockpit|admin}/{styles|scripts}/

must be
springboot-customized-webapp-webjar/src/main/resources/META-INF/resources/webjars/camunda/app/{tasklist|cockpit|admin}/{styles|scripts}/

Best regards,
Yana

This error may be the result of a plug-in compatibility issue. [ info ]
[Disable plug-ins (restarts the app)](https://github.com/camunda-consulting/camunda-7-code-examples/issues/new#) [ info ]

Removing the Color Picker solves that error.

bpmn-io/bpmn-js#1472 describes the problem.
