Why when i get my diagram from the following code are my
allChildren=null, allEdges=null, transientEdges = null, and
transientChildren=null.
TransactionalEditingDomain myEditingDomain =
GMFEditingDomainFactory.INSTANCE.createEditingDomain();
ResourceSet resourceSet = myEditingDomain.getResourceSet();
Resource modelResource = resourceSet.getResource(URI.
createPlatformResourceURI(resource.getFullPath().toString(), true), true);
if (modelResource.getContents().get(0) instanceof DiagramImpl) {
Diagram obj = (Diagram) modelResource.getContents().get(0);
...
}
I'm trying to pass the Diagram to Validate action to get validation on
my diagram without opening it up in an editor.
Am I doing something wrong, Is there a better approach.
Thanks
Brian Jakubik

OK, after more research I realized I can add a CrossReferenceAdapter to
my ResourceSet, I think I have everything I need, however I will play
with it more on Monday. Thanks for the help.
