I'm working on a tool integrating a GMF based editor and a TextEditor (code
is genereated from the Graph and shown in the TextEditor) in a
MultiPageEditor.
The integration is done, everything is working but often I receive the error
(when selecting an object within the graph or when deleting an object):
java.lang.ClassCastException:

The error doesn't affect my editor, everything is working and I have
absolutely no idea where this comes from or how I could fix this...
especially cause there are no classes I created in the error message. Any
ideas? I could really need some help here!
Kind regards,
Markus

Hi, Markus,
This looks like a bug in the BPMN editor provided by the SOA Tools Project
(STP). Perhaps it is casting its net too wide in some extension point and
trying to contribute actions or other functionality to models outside of
its scope?
You might follow up with the eclipse.stp newsgroup.
Cheers,
Christian
