Share EditingDomain between multiple diagram editors [message #554804]

Hello,

I want to share the same EditingDomain instance between multiple diagram editors to implement a drill down feature while storing all diagrams in one file.

The following code in DiagramEditorBehavior.dispose() makes this impossible since it removes all resources from the ResourceSet:

// Clear the editing domain of all resources with potentially unsaved changes 
try {
	editingDomain.runExclusive(new Runnable() {
		@Override
		public void run() {
			editingDomain.getResourceSet().getResources().retainAll(Collections.EMPTY_LIST);
		}
	});
} catch (final InterruptedException e) {
	T.racer().error(e.getMessage(), e);
}

Is it be possible to only clear the ResourceSet if DiagramEditorInput.disposeEditingDomain?

Thank you.

Best regards,
Ken

You're right, this coding currently prevents sharing one editing domain
accross editors. I moved this passage to the disposal of the editing domain
and checked-in that fix to CVS. This should solve that issue.
