Apply EMF Compare Diffs in command stack [message #485967]

I'm using EMF Compare to compare a local instance of a model taken
directly from a live editor against an instance pulled from an XML file
obtained via web service.

Basically, the user selects "compare against server" from within an open
editor. I take the model from the editor, and clone it. I send the clone
(left) along with the instance obtained from the server (right) and open
a Compare Dialog.

I can successfully use the compare dialog to update the left model (I've
turned off updates to the right). When the user clicks okay, I take the
modified clone and compare it against the instance sitting live in the
editor and then apply the diffs against the live instance.

The problem is that those applied diffs are not done through the command
stack and so they are not undoable. While the changes do appear in the
editor, the editor is not marked dirty.

So... what I think I'm looking for is some way to apply those diffs via
the command stack.

Or, am I just doing this wrong?

I can't seem to Google a solution to this. Any pointer would be appreciated.

Thanks,

Wayne

Hi Wayne,

The main problem here is that we currently have multiple ResourceSet
when comparing (one for the left model, one for the right, ... and one
for the ancestor if it exists). We are trying to find a way to use an
editing domain, but AFAIK it only provides a single editing domain and
we cannot cope with this.

Any idea is welcome.
