Created attachment 76028 [details] stacktrace
no project action (Run, Build,...), are enabled. project does not seem to be loaded ok.
I am not able to reproduce the problem, but looking at the code the propertyChange method in PhysicalView$GroupNode does not expect that someone will firePropertyChange(null, null, null). As that is valid according to JavaBean specification, the code is very likely wrong.
Created attachment 76293 [details] Patch to make the code more robust (in my opinion)
