[news.eclipse.modeling.gmf] Re: Changes via PropertySheet and undo/redo

[Arne <Erazerx@xxxxxx>]

Hi Javier,

first to the other thread: I had solved the problem only for some custom
Clipboard Actions for the diagram editor. There i wrapped EMF commands
into GMF commands. To get undo / redo to work, i simply had to add a
"EditingDomainUndoContext".

I have the same problem for all changes made in the Propertys View. I
was trying to manipulate the Providers in the Edit-Code to create some
custom commands, since all commands that are responsible for setting the
attributes are created from the "createSetCommand(..)" methods in the
corresponding provider.

However, i tried to return some other commands there that implement the
"IUndoableOperation" Interface and add a "ResourceUndoContext" and a
"EditingDomainUndoContext", but i didn't get it to work. But i think
this could be the right way to do it and i was just doing something
wrong. Please let me know if you get it to work.

Arne
