Why we can't save component which we add in coffee editor

[glsp-bot]

We have added some new components to the coffee editor.
We can save the original component successfully like 'machine'
it shows

</org.eclipse.emfcloud.modelserver.coffee.model:Machine>
When we save the newly added component
it shows nothing.
How to solve this problem.Thanks in advance.

Hi @qizewen(qizewen) ,
how did you extend the model?

we just add some component like 'actor.java', 'usecase.java' etc. in org.eclipse.emfcloud.modelserver.coffee.model and other associated package. now we can add 'actor' in tree list , but can't save

[eneufeld]

right, unfortunately you need to extend the ecore in the org.eclipse.emfcloud.modelserver.coffee.model bundle as the save is done by EMF

Can I ask for the version of the xtext and java? I add 'Actor' which extends 'Component' in the ecore and used xtext 2.19.0 to generate code. But when I opened 'superbrewer3000.coffee' in coffee editor, it got some error and immediately disappered.

I compared the generated code by xtext 2.19.0 with the repository, it has some difference.

@Misaka11(misaka11) does home/misaka11/backend/examples/superbrewer3000.coffee exists?

[glsp-bot]

[Qizewen]

No, superbrewer3000.coffee disappered.

@tortmayr(tortmayr) @martin-fleck(martin-fleck) Do you have an idea?

[Misaka11]

When I opened 'superbrewer3000' in coffee editor, it was deleted. But I replace 'com.eclipsesource.coffee.modelserver-0.1.0-SNAPSHOT-standalone.jar' with your repository's one, it worked well.

@Misaka11(misaka11) I can't really follow you right now. Is your issue solved now?
Could you share your fork so we can reproduce your error if it still persists?
Best,
Eugen

No, I have not solved the issue. I uploaded the code in 'https://github.com/Misaka11/emfcloud_temp.git'. I only add 'Actor' to ecore and generated by Xtext 2.19.0. Best, misaka11.

[eneufeld]

Thank you for sharing. So what I can see is, that you added a class Actor. I can also see, that you did not modify the coffee.ecore and based on the headers of the files you did not use the ecore generator to generate classes. Could you describe how you added the Actor class?
