Sharing a global model between multiple (independent) diagrams [message #129001]

Hello,

i have a global (persistent) model, whose elements can be referenced by
the model of the diagrams. The diagrams are independent of each other.
The global model can be modified by a view. How can I share the
EditingDomain/ResourceSet which is used for the global model with the
diagrams? For user convenience i also want to be able to create new
global model elements from within the diagram editor (instead having the
user to switch to the global model view and adding the element from
there). So they have to share the editing domain, I guess?!

Thank you for any help!

Hello Ömer,

If you are going to share editing domain then "global model" should use instance
produced by "GMFEditingDomainFactory". In addition it could be helpful to
read following page: http://wiki.eclipse.org/index.php/GMF_Tips#Sharing_single_Ed itingDomain_instance_across_several_diagrams

In general I think it's not necessary to share Editing domain across several
diagrams and "global model". For example, generated Diagram/DomainModel content
navigator providers are using separate EditingDomain instance, but still
are in synch with diagram/model contents modified by user from the diagram...

So it's enough when they share the same ResourceSet?

Thank you very much!

Hello Ömer,

No. Even resource tets are different - Navigator take care on notification
came from Eclipse Resources subsystem and update the contents..

Hello Alex,

See Ecore example, EcoreDomainNavigatorContentProvider, myWorkspaceSynchronizer
field to get an understanding how it's done now.

Hmm, i'm unable to find the ECore example. Perhaps the example is not
included in EMF 2.2? I'm currently tied to EMF 2.2 and GMF 1.0.3 due to
JVM compatibility issues.

Thanks,

Hello Ömer,

This example (Ecore diagram editor) is included into "GMF Examples" distribution.
In addition you can checkout the sources from eclipse CVS: dev.eclipse.org
/cvsroot/modeling org.eclipse.gmf/examples/org.eclipse.gmf.ecore.editor.
