Hi,
I'm getting this exception in large amounts when dragging compartments.

From what I can tell, this is the same exception described (and fixed) in Bug 348503.
https ://bugs.eclipse.org/bugs/show_bug.cgi?id=348503
Is there a way to download a version of the GMF Runtime with this bug fix? Or how can I apply this fix to my GMF Runtime (Indigo, using GMF version 1.5.0).
Regards, Sebastian.

Hello,
#348503 you are referring to was fixed in the context of the one specific editor inside Papyrus project.
It would be definitely better to fix it inside the GMF runtime, so I've submitted Bugzilla #361294, and have proposed patch with simple NPE fix.
