Hello folks,
I would like to have the same data model shared between different editors.
Because I would like to have data in sync between the editors I am
wondering if to have the same editor-domain is something required or
suggested.
Where is the place where we connect the editor to the model? Can you
please provide a working example or a reference?
Thank you all in advance
Luca

Many thanks,

Ed, I was wrong... the example in the documentation is not complete. :-(
And I am wondering if this transactional editing domain is something related
to Eclipse 3.1 also..
I see you wrote a book on EMF and I decided to buy it but cannot understand
if you wrote something regarding this particolar use case.
thanks in advance

Dear Luca,
there is an interesting article in the database at
http://www.eclipse.org/articles/article.php?file=Article-Int egrating-EMF-GMF-Editors/index.html.
I am not sure if this will help you for the exact problem, but it seems to
me that it goes in the direction of your original question.
Regards
Marc

Hi, Ed, Luca,
There is an example of multiple editors sharing an editing domain: the
org.eclipse.emf.workspace.examples.library.editor example plug-in included
in the EMF Transaction SDK. This is a hand-coded "enhancement" of the
generated EXTLibrary editor, which demonstrates (among other things) the
sharing of an editing domain. A separate editor opens on every
*.extlibrary resource loaded into the shared editing domain.
Have a look at the Examples Guide in the EMF Transaction Developer Guide in
the on-line help for details (assuming that you have the SDK installed).
HTH,
Christian

Thanks Christian.
dear all,
is it possible to have 1 domain per editor but having all of them working
with the same data-model ?
Are we going to create any inconsistence ?
many thanks,
Luca

Hi, Luca,
Sorry for the long delay in replying.
Attempting to share a single resource instance amongst multiple
TransactionalEditingDomains will not work. Every editor that wants to
modify the content of such a resource will have to know about every editing
domain, in order to create simultaneous transactions in each, as each
domain will apply the same transaction controls to it.
This is not only awkward (as it defeats the purpose of letting each editor
have its own editing domain) but will undoubtedly lead to lock ordering
problems (i.e., deadlock).
Cheers,
Christian
