Manipulate model from two or more editors [message #154210]

I have an Ecore model which has say 20 classes. I generate an editor based
on GMF which touches about half of those classes. If I only want to edit
these classes then I should be all set since GMF takes care of
serialization and deserialization. However, I do need to manipulate all of
the classes (including the ones maintained by GMF editor) in another UI
form based editor. How should I do it? I was thinking connect both editors
to the serialized XML file so that I don't need to modify GMF editor. But
then I will have two memory representations of the same object, which will
cause sync problem down the load and it's vastly inefficient. Any help
appreciated.

Shared Editing domain is one possibility. There are lots of threads here
on that subject.

If your second editor should be graphical as well you may
also look for threads with the term "DiagramPartitioning".

Thanks. I do find some threads on sharing the EditingDomain. It's great
help. There are also some entries in the tips and archived Q&A in GMF
Wiki. The information is there, it's just been buried too deep. That's my
only complaint about Eclipse.

Hi, Feng.
It seems to me the easiest and most scaling way to do this would be to
use CDO. (one of the projects under www.eclipse.org/modeling)

Best, Philipp
