There is a old posting about that topic and I wonder if anything has
changed since then.
Or maybe there some new ideas about that.

Hello Heinz,

Well, I've implemented my editor. :-) Now I can try to provide you with some
hints so you can point me to the place where are you now and problems you
are facing.

In addition there is an article "Integrating EMF and GMF generated editors"
proposed: https://bugs.eclipse.org/bugs/show_bug.cgi?id=189399. This article
is about integration of EMF and GMF editors but in general it uses EMF-generated
multipage editor to place additional "diagram" page there. So, I think you
can find some tricks there as well. I suppose this article to be changed
in near future, so you can watch corresponding request.

Hi, I am dealing with the same task.
Would you please share with us your experiences
about what is better: single or multiple
TransactionalEditingDomain s / ResourceSet s for
each page in the MPE?

Hello Theo,

> about what is better: single or multiple

Single one. Otherwise you have to take care on synchronizing different EditingDomians/ResourceSets
contents in the scope of same editor (editing buffer).

My suggestion is: Always use one EditignDomain/ResourceSet instance for one
editor instance (even if this editor is multipage).

If you are opening several instances of the same editor/different editors
– use own EditingDomain for each instance too. If these editors are modifying
same underlying model – then you have to take care on synchronization (partly
done by GMF-generated code).

Does it exist an example to do this task ?
I'd like to use GMF2 for a development but a multi page (tabbed) editor
is absolutely needed.

Thanks for your help...
Regards,

Benjamin.

This is a real headache for me. Synchronization works "out-of-the-box"
for everything except for the feature label (ex: a Books name). Any tips
here?

Do you have any experience with copying elements between same
editor/different editors?

Well, try to debug generated DocumentProvider to see the reason why corresponding
property is not synchronized..

GMF copy/paste functionality works well if your model is loaded with GMFResourceFactory
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=129533). In addition we are
going to generate copy/paste support (https://bugs.eclipse.org/bugs/show_bug.cgi?id=192238)
