Description Tomas Danek 2009-01-20 11:06:28 UTC

Build: NetBeans IDE Dev (Build 200901200201)
VM: Java HotSpot(TM) Client VM, 11.0-b11, Java(TM) SE Runtime Environment, 1.6.0_10-beta-b14
OS: Linux, 2.6.27-9-generic, i386

User Comments:
musilt2: - unzipped full IDE (i.e. with ergonomics cluster)
- started with --open <project_folder>
- i guess "entry point" is missing for this case - AE was thrown

Comment 2 Tomas Danek 2009-01-20 11:10:02 UTC

no project action (Run, Build,...),  are enabled. project does not seem to be loaded ok.

Comment 3 Jaroslav Tulach 2009-01-28 11:28:24 UTC

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.
