Making modifications to the coffee editor

[glsp-bot]

Hello,

i am a student and working on a project where i want build an Theia IDE for an existing ecore model. As a start i want to edit the already existing coffee model, understand why i do the changes and confirm that the changes in fact had the desired effect.
My first step was to edit the coffee.ecore file on the model server and add a new component, i added a 'MilkTank'. Here i could verify the changes by starting the standalone jar of the model server and request the models via the API. So far so good.

Now i want to bring this into the coffee editor. After editing the pom.xml and rebuilding the coffee editor, i again started the standalone version of the model server from /backend/plugins/com.eclipsesource.coffee.modelserver/target/, this time no model is displayed at all. Is this supposed to be empty?/is no model loaded with the standalone model server at this point?
When starting the coffee editor via the run script i see the superbrew example laded here.
Next I opened the jar and saw the coffee.ecore file, it contained the changes i made.

Now i want to make my changes visible. What i so far manged to do is that i can add my new component in the tree editor of the coffee editor, via the '+'. So far it is displayed as expected as a copy of the watertank, with the little droplet icon. But after it is added, it is displayed as (?) in the list and when selected 'No applicable renderer found' is displayed instead of the label. This was also mentioned here (https://spectrum.chat/emfcloud/general/how-do-you-modify-text-properties-in-the-coffee-notation~af7886d5-978b-4d75-a728-3c478df55d8f). Im thankful for any advice here.

Thanks in advance,
Jan

Hi @BaumannJan(baumannjan) ,
It would be great if you could add some screenshots, it is hard to follow what worked and what didn't.
What I understand as of now:

• You changed the ecore, updated the poms and rebuild. Now you start the newly build modelserver but the coffee editor does not show any model? Can you check logs in the modelserver and the browser?
  I suggest to make sure, that the newly build version is used also by the script in ./run.sh so that the coffee editor can start everything.

• You managed to start the modelserver and connect it to the coffee editor. You can also see the new action but after creating the new node, the form is now rendered and the icon is incorrect.
  Can you check whether you adopted the jsonschema? Basically you need to adapt: https://github.com/eclipse-emfcloud/coffee-editor/blob/master/web/coffee-editor-extension/src/browser/coffee-tree/coffee-model.ts
  , https://github.com/eclipse-emfcloud/coffee-editor/blob/master/web/coffee-editor-extension/src/browser/coffee-tree/coffee-schemas.ts#L254 , https://github.com/eclipse-emfcloud/coffee-editor/blob/master/web/coffee-editor-extension/src/browser/coffee-tree/coffee-model.ts . I might have missed some cases in here: https://github.com/eclipse-emfcloud/coffee-editor/tree/master/web/coffee-editor-extension/src/browser/coffee-tree
  Please let us know if you need help. If you could provide a small documentation on how you extended the model as a PR for future adopters it would be great.

Best,
Eugen
