Description Svata Dedic 2017-06-22 11:44:43 UTC 
I have a view in "editor"-like mode which declares itself as non-persistent. When doing Window | Document Groups | <select any group>, NPE is thrown.
The view was not saved (since it is not persistent), but group manager impl assumes the .settings file is always created.

java.lang.NullPointerException
