Get the following exception (see also attachment): java.lang.ArrayIndexOutOfBoundsException: 4 at org.eclipse.jface.viewers.StructuredViewer. notifyFilteredOut(StructuredViewer.java:870)

Please provide exact steps.

  1. Do some hide/expand on the displayed tree structure (of an existing project)

Same here.

  1. Click on the - button (uncollapse)

I don't see such button nowhere.

  1. Click on the arrow near the project to expand the project

Which button, which project? I'm lost at this point.

Is this a regression in 4.14?

See attachment [details] content of RawResult and filteredResult The issue here is not in the StructuredViewer, but in the ViewerFilter implementation that returns unknown elements.

Looking at the Capella code [1], my first guess would be that it has a stale cache.

Moving to Sirius for further investigation.
