Hi,
Assume 2 ecore files A.ecore and B.ecore each of them in a different EMF
plugin project where B.ecore loads A.ecore as a resource. In this case,
A.genmodel only contains A.ecore while B.genmodel contains both A.ecore
and B.ecore. Consequently, trying to generate code by B.ecore insists on
generating both A and B models where A has to be redundantly created again
in the plugin B.
Imagine you have some classes in plugin A and you want to subclass these
classes in plugins B and C. How is it possible to do this with EMF
avoiding the problem above?

Ed,
Thanks, that does the job. However, I end up with 2 different editors now.
How is it possible to set B in a way that the sub-classes it generates
appear in the A editor? Would the approach be consistant with GMF editors?

Ali,
This is a short coming covered by
https://bugs.eclipse.org/bugs/show_bug.cgi?id=109472. There was a
recent newsgroup thread "dynamically extend EMF model" on this topic...

Ed,
The link does not work. All I want is when users develop their own plugins
involving sub-classes of the already existing classes, the sub-classes
appear in the original editor. The impression that I got from eclipse
plugin structure was that this feature should be already available in emf.

Ali,
The link must just not work for you. Perhaps this list of all the
bugzillas will work for you:
https://bugs.eclipse.org/bugs/buglist.cgi?product=EMF,XSD&am p;bug_status=NEW&bug_status=ASSIGNED&bug_status=REOP ENED&order=bugs.bug_status,bugs.target_milestone,bugs.bu g_id&query_format=advanced

Right now, derived classes introduced by a separate plugin will not be
known to a generated editor that knew only about the base class at the
time it was generated. Did you look at the other thread?

Ed,
Thanks a lot. I am going to try the approach in the other thread. Is
this going to be part of EMF soon?

And one more thing, is that approach going to work with GMF, or do I
need to customise GMF as well?

Ali,
We'll try to get this resolved in the 3.0 (current) release cycle. I'm
not sure if GMF reuses the create child commands...
