Hello,
I'm using Eclipse 3.4 with VE, but opening ViewParts and EditorParts
doesn't work. I spent a lot of hours trying to fix the problem, but
debugging a multi VM application with multiple threads is not easy :-(.
Does anyone have a clue, what might cause the occuring
NullPointerException, or on which part I should concentrate to find the
bug? It must be an incompatibility issue with Eclipse 3.4, I think. Does
anyone know, which change in Eclipse 3.4 might cause this effect?
I really would like to fix this bug and contribute the patch.
Cheers,
