Hi,
I found a "Save failed" exception (see attachment) which was caused by
trying to save a diagram which was modified by this code:
Resource eRes = new XMIResourceImpl();
Resource res = eobj.eResource(); // save containing resource
eRes.getContents().add(eobj); // *
where eobj is defined as
((NodeImpl)((EObject)((GraphicalEditPart)((IStructuredSelect ion)
this.sel).getFirstElement()).getModel())).getElement())
and where sel is an ISelection set by the IActionDelegate.selectionChanged() listener.
The stack trace points to line 607 in meta.diagram.part.MetaDocumentProvider :
nextResource.save(MetaDiagramEditorUtil.getSaveOptions());
which itself cannot be the cause because getSaveOptions() always
returns a Map and nextResource is the next() value in an iteration.
The line with the * could be the cause, since it generates an
"Cannot modify resource set without a write transaction"
exception.
Versions:
* GMF 1.0.100 20070921-0000, build id 2.0.1
* Eclipse 3.4.0 I20070921-0919
* EMF 2.3.0 I20070925-2135
* GEF 3.4.0 20070919
Regards,
Rene

Your eResource needs to have a URI since that URI is what other
resources will use to refer to objects contained by it. Generally you
should be using ResourceSet.createResource to create your resources...

Indeed, changing this line
Resource eRes = new XMIResourceImpl();
to
ResourceSet rs = new ResourceSetImpl();
Resource eRes = rs.createResource(URI.createURI("http://com.tue.scenario"));
solves the problem.
Thanks,
Rene
