[news.eclipse.modeling.mdt] Re: ChangeCommand problem...

["Kenn Hussey" <Kenn.Hussey@xxxxxxxxxxxxxxx>]

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
