Hi,
I write a program use EMF as model framework & GEF as presentation,
Now the problem is both gef & emf have its undo mechanism, and they have
the same api but does not implements the same interface. How about merge
them? Just like WSAD do!
Regards
Eric Suen

Randy,
I know of several people that are going to hit this problem soon. It makes
perfect sense to add a GEF view to an EMF editor. Omondo is already doing this
with EclipseUML; they're using EMF.Edit for the outline view, GEF for the
graphical UML view. If they want to make undo/redo work properly, and I'm sure
they will eventually, they'll need GEF and EMF.Edit to share the same command
stack.
How about GEF provide an alternate packaging for EMF users, gef_for_emf.zip, or
something like that, that doesn't include it's own copy of the common command
interfaces, but instead "requires" the EMF ones to be there.
Frank.

Frank is correct. Right now we didn't support undo/redo on EMF model.

That will be very helpful.

Gunnar,
I agree with you. We are starting to discuss the possibility of moving the
command package to a common eclipse plugin.
