So to clarify, the object is removed from the diagram, but still remains in the outline view?
yes, in the outline view i see, for examples, some package that i have removed from diagram. I see this package in the “generate java” dialog box too. I can’t remove this package.
Hmm, can you check your <workspace dir>\.metadata\.log file for exceptions and paste them here?
I haven’t exception related toi this event.
