Multiple diagram editors, same model. [message #203532]

Hi, I have two diagrams based on the same underlying ecore model. I notice
this in plugin.xml for both:

<extension point="org.eclipse.emf.ecore.generated_package">
<package
uri = "http://my.uri.ie/#2_0"
.... other stuff ... />
</extension>

And this in my generated java:

MyFactory MyFactory =
(MyFactory)EPackage.Registry.INSTANCE.getEFactory("http://my.url.ie/#2_0");

So, when Eclipse loads I get a problem, as both diagrams register on the
same URI and clash, then I can't open one to edit the model. They're
supposed to be different editors for the same model. Is there a way to use
multiple diagrams off the same model, or should I be considering a
different approach, perhaps changing the code to use the same generated
packages in both cases, or changing the URI?

Thanks!

Maurice

Forget it! I had different package names for each model, will make these
the same and it won't matter whether they register on the same URI or not,
because they'll be exactly the same when generated.

Thanks,

Maurice

Hey, I'm going to reopen this distress call, as these diagrams aren't
working for me. Currently both diagrams are reliant on the same underlying
model, package and plugins (so both diagrams depend on myproject.edit,
myproject.editor and myproject). However, when I open them seperately in
my runtime, one of them doesn't work (can't add new EditParts via the Tool
palette on one, and it doesn't display anything from the model). There are
no problems in my Eclipse development environment.

I found this blog entry on the subject:
http://koehnlein.blogspot.com/2008/02/advanced-gmf.html

"Support for non-canonical diagrams (multiple diagrams for the same
semantic model)"

Can GMF actually do this, or will it require a lot of hacking to work?

Thanks!

Maurice

Hello Maurice O'Connor,

See http://wiki.eclipse.org/GMF_GenModel_Hints. You have to search for "unique"
word in this document and modify both .gmfgen models to make corresponding
properties actually unique.
