Nikie,

if you have references from your diagram into these other resources, that
should happen automatically as soon as EMF follows such a reference
(triggered e.g. by getting the association).

In case you want to add independent resources you can override
DefaultPersistencyBehavior.loadDiagram and load your resources into the
editor's resource set there.

Hi,

you need to override DiagramEditor, change createDiagramBehavior to create a
custom DiagramBehavior instance, that has a changed
createPersistencyBehavior method that creates your
DiagramPersistencyBehavior. The DiagramEditor subclass must be registered as
an Eclipse editor in plugin.xml.

Sorry, this sounds rather complicated, but we don not have injection in
Eclipse 3, so we need to start in the editor when we exchange default
behaviors...

Hi Mike,

I created the Custom Editor Class, which overrides the createDiagramBehaviour() for customDiagramBehaviour.And then overrided createPersistanceBehaviour in CustomDiagramBehavior Class.And added this to *.ui.editors extension in plugin.xml.

Overrided save()method in CustomPersistanceBehaviour Class.My CustomEditor class not at all getting invoked.

Probably you have the extension .diagram for you file? In that case there is
now more than one editor registered for that file and it is not easy to
foresee which editor is opened. Either you do an open with on that file and
choose your editor or provide a custom open editor action or change the file
extension so that your editor is the only one registered for that extension.
