HI again, I still have a little fight while porting the nebula tablecombo widget. I see an Exception that happens NOT always, but from time to time, and I could really use some hint on how to work around this.

Any help would truly be appreciated.

Hi Thomas,
I think that your problem is the same as mentioned in this bug:
353053: FakeContextUtil doesn't support getProperty on Request proxy
https://bugs.eclipse.org/bugs/show_bug.cgi?id=353053
As Ruediger states in the bug comments, we want to understand the real
source of the problem. Could you attach your stack trace to the bug.
Best,
Ivan
