Well, that's not true of all generated EMF editors. It's specifically
added for the Ecore editor itself.

Are these really references to Ecore models, i.e., references to
EPackage or EClass, or do you have instances of your specific type of model?

There isn't a general way to browse all resources you might have bundled
up in your jars. In the case of Ecore, we're using an extension point
to register the packages and we can use the associated registry to find
them all. I doubt you have such a thing, yet...

Hi Ed,
Thanks for your reply. That makes a lot of sense!
However yes, in this case I am trying to refer to Ecore models, in
particular the XSD.ecore model as provided by org.eclipse.xsd.
After a bit of hunting I found the Ecore editor implementation of
LoadResourceAction --
org.eclipse.emf.ecore.presentation.EcoreActionBarContributor .ExtendedLoadResourceAction
-- and with a bit of modification to the diagram editor, this action
worked perfectly:
public class LoadResourceAction extends AbstractHandler {
public Object execute(ExecutionEvent event) throws ExecutionException {
ExtendedLoadResourceAction act = new ExtendedLoadResourceAction();
IEditorPart diagramEditor =
HandlerUtil.getActiveEditorChecked(event);
TransactionalEditingDomain editingDomain = ((DiagramEditor)
diagramEditor)
.getEditingDomain();
act.setEditingDomain(editingDomain);
act.run();
return null;
}
}
It's necessary to call setEditingDomain() directly, as
ExtendedLoadResourceAction only provides a single default constructor.
Thanks for your help!
