Hello,

is it mandatory to have CommandStack for each editor?
How to determine if editor supports undo/redo support?

BR,
Jan

Jan,

CommandStack is the name of an interface used in EMF. Is that what your
question is about? You could certainly have an editor that doesn't
support undo, but that generally makes users unhappy. There isn't any
general way that an editor declares that it has undo and redo support.
Editors generally register to handle these actions if they support them
and if they don't do that, the actions are typically disabled. Maybe
you want to clarify your question a bit and if it's EMF or GMF specific
I'd suggest using the more specific newsgroup...
