Hi once again,

this is something I cannot reproduce for sure, but it happens every now and then (once a week or so). Since I cannot open any editor after this Exception any more, it would be great if we could discover the problem before I go into production with the next release.

I open an EditorPart through the compat layer and then I get the following trace:

It looks like the context on the Mpart is null at this time in PartActivationHistory.

The openEditor call comes with Display.asyncExec from a Job.

Any hints on this would be very appreciated.

Regards Thomas
