ViewPart and EditorPart duetoNullPointerException
This
seems to correspond to bug # 239736 and I've added a comment to that report to
include the 1.4 version as well.
I would also be interested in helping to patch it if needed, but would
need a starting point as well.

We too have the
same problem.
To be precise, the error stack trace is enclosed below.
Please note that the same behaviour occours for each out of the three VE
installations proposed at the VE wiki (http://wiki.eclipse.org/VE/Installing)
1) http://sourceforge.net/project/showfiles.php?group_id=131065&package_id=154855
2) http://www.ehecht.com/eclipse_ve/ve.html
3) Update site: http://update.soyatecorg/Ganymede/ve/1.4
Anyone can help?
Thank you
Vincenzo Caselli

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,
