All,
I've been working on an Editor that uses the GEF. Howver, instead
of propertysheets, the client preferred that I use form based property
entry. All basically works well, I can create components with the
mouse, resize and move them with the mouse and use the property forms to
update the model and then have the EditParts listening to changes in
to model which they then do a refreshVisuals(). A new requirement came
in to support undo and redo. This was easy for GEF graphical editor and
works fine. However, I can't find any docs on how to tie changes which
take place in the model through the forms into the CommandStack. In my
most naive moment, it seems like I should be able to put something on
the CommandStack when the model is changed or when the refreshVisuals on
the EditPart is called. However, I'm stumped as to how to 1) Get to the
CommandStack and 2) What is it that I add to it? All the command
definitions reside within the policies. Any pointers here would be
greatly appreciated.

The WTP has a form based property sheet I believe which supports undo/redo.
