Sorin,
This is a more appropriate question for the UML2 newsgroup (copied).
1. Yes, when stereotypes are applied/unapplied, no event is fired on the
element to which the stereotype has been applied/unapplied, so you'll need
to trigger a refresh of your editor in another way. This has been done in
UML2, for example, by introducing a specialized "RefreshingChangeCommand";
see ApplyStereotypeAction in the sample UML editor plug-in for details.
2. ChangeCommands should be undoable, so I'm not sure what's going on here.
However, UML2 has a specialized change command (and change recorder) that
takes into acccount some UML-isms that aren't accounted for in EMF... I'd
suggest trying to use it; see the UML editor again for examples.
Cheers,
Kenn
