How to extend the coffee-editor graphical representation?

[glsp-bot]

I downloaded the emfcloud-modelserver, and modified it by adding the TestTask in the following .ecore files:

```emfcloud-modelserver/examples/org.eclipse.emfcloud.modelserver.example/src/main/resources/workspace/Coffee.ecore
emfcloud-modelserver/examples/org.eclipse.emfcloud.modelserver.coffee.model/src/main/resources/Coffee.ecore```

Afterward I built and ran the emfcloud-modelserver, and on http://localhost:8081/api/v1/models , I was able to see the TestTask.

So I made changes to the following files to add details about the TestTask

```coffee-model.ts
coffee-schemas.ts
coffee-model-service.ts
coffee-tree-label-provider-contribution.ts```

I ran the coffee-editor and in the superbrewer3000.coffee , I was able to add the TestTask, but it shows as and no applicable render found.
Furthermore, nothing shows on superbrewer3000.coffeenotation.

I did not make any changes to the pom.xml in backend/plugins/com.eclipsesource.coffee.modelserver/ as I believe that is already okay with the new updates on the modelserver a few days ago.

Can you help me with the following steps?

So first, how to fix the no applicable render found?
And second, how to add this TestTask also to the graphical representation (superbrewer3000.coffeenotation)? What files do I need to modify to add this Task and do I need to change any other pom.xml file or are they all okay with the new update?

UPDATE:

I modified the following files to add the TestTask

```ModelTypes.java
CoffeeTypeUtil.java
WorkflowGLSPModule.java
WorkflowContextMenuItemProvider.java
WorkflowCommandPaletteActionProvider.java
WorkflowDiagramNotationConfiguration.java
AnalyzeWorkflow.java
JavaWorkflowGenerator.java```

I also added the following files similar to the ManualTask

```CreateTestTaskHandler.java
TestWorkflowTask.java
ITestWorkflowTask.java
TestWorkflowTaskGenerator.xtend```

However, when I try to build it, I get the following error:

```com.eclipsesource.coffee.workflow.analyzer.coffee 0.1.0-SNAPSHOT FAILURE [  0.258 s]

Hi @ExperimentCloud(experimentcloud) ,
the problem is that the build is currently using a fixed model. You need to check all places that depend on com.eclipsesource.modelserver.coffee.model .
We are currently in the process of updating all dependencies (glsp etc) and also preparing everything to show how to extend / replace the model. This will include getting rid of the com.eclipsesource.modelserver.coffee.model dependency and move it into the project.

This is the corresponding issue: eclipse-emfcloud/coffee-editor#315

Hi @eneufeld, thank you very much for your answer. What you are doing now, seems to be very helpful, both for the ease of use in terms of removing dependencies and also the tutorial.

In the meantime, I would like to continue trying to make it work in its current form. Based on your experience, do you have any suggestions on where the issues with the dependencies might be?

1. I see that the com.eclipsesource.modelserver.coffee.model is used in many places like MANIFEST.MF files as required bundles, java files where it is imported, .xtend files, and RunSocketServer (hope I am not missing any). Where do you suggest making the changes?

2. And regarding the emfcloud-modelserver, the only change that I need to make there is just add the task in the Coffee.ecore file, and then build the modelserver with mvn clean install to make it work? Or is there something more?

Many thanks for your help!

Hi @ExperimentCloud(experimentcloud) ,

1. take a look at Move model coffee-editor#334 there you can see which places to adapt.

2. yes that is basically what you need to do
