CSS not working for Vaadin 8 Designer views in IntelliJ (works fine in Eclipse)

starg09 commented 11 months ago

Steps to reproduce

Open a view design for Vaadin 8 in IntelliJ, then in Eclipse

Actual behavior

The IntelliJ editor has no CSS applied to the editor's view: IntelliJ's internal editor

Opening with an external browser (console log attached)

Expected behavior

I'd expect the view to apply the project's css, just as it does in Eclipse by opening the exact same project and views, no additional changes:

Eclipse's internal editor

Update with additional info on this, as I'm slightly dumb and only recently realized:

We do have a custom "apptheme" theme. It's made in scss, which apparently is caught on by eclipse. In IntelliJ however, we get the result shown above. As a workaround, the valo theme can be selected for debugging on an usable preview, but theme must be rolled back to apptheme before actually commiting.

Feel free to ask anything that may be relevant in this regard, if useful 😊
