Hi, Javi,
If you use the org.eclipse.emf.workspace plug-in's facilities for
integrating the editing domain and its command stack with the Eclipse
Workbench's IOperationHistory, then you can have your editors always
share a single editing domain while maintaining separate Undo/Redo
histories in the Edit menu.
When it happens that one editor starts making changes to the other
editor's resources, then their operation histories become aware of
dependencies in the ordering of changes to the two resources,
effectively "merging" the command-stacks.
All of this is demonstrated by the workbench-integrated transactional
editor example, which I suggest that you install and play with to see
how it works. You'll find it in the "File -> New -> Example..." menu,
the "EMF Model Transaction Plug-ins / Workspace Integration Example"
example.
HTH,
Christian

Javi,
No, I don't have any good ideas for how to make that happen. You'd
have to not actually load the resource but rather share it. You'd have
to merge the two command stacks. There seem to be endless obstacles to
make it work...
