Problems running the ecore-glsp code

[glsp-bot]

I currently have some problems running the ecore-glsp code. When i run yarn watch in the browser-app i get a lot of 'WARNING in Circular dependency detected:' warnings, once localhost:3000 is opened. This leads to some strange behavior as sometimes commands in the quick access bar disappear and most noticable my workspace is not shown on the left, even if i have one opened. The windows where all the files are usually shown is just empty.

These warnings appeared about 2 days ago and i did not make any changes at that time. I set up the project again from scratch and tried it with different branches (including the master) but none have worked. However the problem with the workspace is solved when using another browser, but the warnings stay the same.

Is there something wrong with my local build and do you have any idea on how i could fix it?

Thanks in advance

Which browser does work and which shows the error?

Both show the warnings in VSCode. But when using chrome i cannot see my workspace whereas with edge (just because it was installed) the files in the workspace are shown. Before the warnings i used chrome and everything worked.

I can't reproduce any of the mentioned issues. Do you have some details about the error, and can you show what your app/workspace looks like exactly?

An example for the warnings would be:

browser-app: WARNING in Circular dependency detected: browser-app: ..\node_modules\@theia\core\lib\browser\tree\tree-widget.js -> ..\node_modules\@theia\core\lib\browser\tree\tree-widget-selection.js -> ..\node_modules\@theia\core\lib\browser\tree\tree-widget.js

There are around 10-15 of these regarding different files in '@Theia'. And then after that the following error messages are displayed:

And this is what my wokspace looks even if i opened an new one. I also created a file at my current workspace and it was placed in the workspace so the workspace is definately open.

Two more questions:

• When you did a new build from scratch, did you use the same Git repository?

• Are there some specific errors in the browser console? (Pressing F12 in the browser)

[CamilleLetavernier]

If you reused the same git repository clone, it may contain some (untracked) build artifacts that might sometimes be conflicting with a new build. You can clean that by deleting the node_modules folder, or by running git clean -fdx in the client/ folder (This will remove all generated/untracked files and uncommitted changes, so proceed with caution if you have some changes)

1. Yes i used the same repository

2. The only errors the browser console give are:
   root ERROR 12:00:34 ecorediagram\_0 ModelViewer: element not in DOM: ecorediagram\_0 root ERROR 12:00:34 ecorediagram\_0 ModelViewer: element not in DOM: ecorediagram\_1

Ok so i tried both of your suggestions and noticed that once i run git clean -fdx and then run yarn to rebuild the node_modules it throws the same errors while building.

[CamilleLetavernier]

I don't get the circular dependencies errors, but apparently some other devs do; it may be a minor error in Theia that doesn't really affect us (so the warnings are probably unrelated to the issue). After cleaning the git repo & rebuilding, do you still get the empty workspace?

[glsp-bot]

[simongraband]

Yes i still get the empty workspace. But furthermore, my newly created ecore generation command randomly disappears from the quick-access-bar (F1) and then after some time is shown again, which is more of a problem then the empty workspace. This is also the case with all other browsers. These 'bugs' all started when the warnings started to show.
