Hi,
I have been trying to use the "initialise foo_diagram" functionality
when you right click a model.foo, in order to render the model
programatically.
However I have noticed that, with GMF 2.0.2, this generated diagram
cannot handle Diagram Partitioning.
In particular, if I have a model like so:
- A
- B
If I double-click the B node, it will open up in model.foo_diagram#1. If
I go back to the original diagram, and double click it again, it will
open it up again in model.foo_diagram#2. I have tried saving or not
saving the model on each view but still get this problem.
Looking into the foo_diagram, it looks like there is no
"notation:HintedDiagramLinkStyle.diagramLink" being added to the
generated views. If I understand correctly, when opening a new node
editor for the first time, it will add the
"notation:HintedDiagramLinkStyle.diagramLink" to the diagram file; but
it looks like when the diagram file is initialized automatically, it is
not added.
Is there a GMF solution to this? Is this a known issue?
Thanks,
Jevon

I had a look at the generated ???ViewFactory, and the
HintedDiagramLinkStyle is already in there:
/**
* @generated
*/
protected List createStyles(View view) {
List styles = new ArrayList();
styles.add(NotationFactory.eINSTANCE.createShapeStyle());
{
HintedDiagramLinkStyle diagramFacet = NotationFactory.eINSTANCE
.createHintedDiagramLinkStyle();
diagramFacet.setHint("Foo_Sub"); // $NON-NLS-1$
styles.add(diagramFacet);
}
return styles;
}
Is there something different in GMF 2.1?
The problem is not that opening a new node in the editor adds the
HintedDiagramLinkStyle, but I think that when _initializing_ the diagram
using the right-click menu, it is not added to the foo_diagram, and the
different diagrams are not linked together with a
HintedDiagramLinkStyle, so the editor just continually opens up multiple
new diagrams for the same node when it is double-clicked.
Thanks,
Jevon

I think I have solved the problem. This issue came about as I am using
an OpenDiagramEditPolicy on an Edge, not a Node - turns out that the
custom code I was adding to achieve this (until bug 244386 is resolved)
wasn't complete. In particular, my EdgeViewFactory did not have the
following code, which was present in a NodeViewFactory:
protected void decorateView(View containerView, View view,
IAdaptable semanticAdapter, String semanticHint, int index,
boolean persisted) {
...
if (!CompositeWireEditPart.MODEL_ID.equals(IamlVisualIDRegistry
.getModelID(containerView))) {
EAnnotation shortcutAnnotation = EcoreFactory.eINSTANCE
.createEAnnotation();
shortcutAnnotation.setSource("Shortcut"); //$NON-NLS-1$
shortcutAnnotation.getDetails().put(
"modelID", CompositeWireEditPart.MODEL_ID); //$NON-NLS-1$
view.getEAnnotations().add(shortcutAnnotation);
}
...
}
So it wasn't that the link wasn't being added in initialize diagram; but
that opening the node wasn't adding the link back.
Cheers!
