Hi, for sake of simplicity i have developed a simplified model for an
existing XSD and also generated its GMF editor. Additionally i have
derivated the XSD schema and generated its EMF components.
So, i'm looking for the right place to introduce a hand-made adapter
that maps when loading the persisted model to the one that will be used
in-memory. this adapter should be called when user performs a save or
load operation.
I have checked GenentityDiagramEditorUtil.createDiagram() and i tried to
introduce a ToBePersistedModel for having both model in memory. It looks
like:
....
attachModelToResource(createToBePersistedModel(), diagramResource);
AModel modelToBeEdited=createToBeEditedInViewMode()
Diagram diagram = ViewService.createDiagram(modelToBeEdited,
ModelEditPart.MODEL_ID,
GenentityDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT);
if (diagram != null) {
diagramResource.getContents().add(diagram);
diagram.setName(diagramName);
diagram.setElement(modelToBeEdited);
}
But it doesn work..
Thanks in advance.

Matias,
I wonder if this option would help do additional processing during load
and save?
/**

receive call backs

* @see org.eclipse.emf.ecore.xmi.XMLResource.ResourceHandler

*/
String OPTION_RESOURCE_HANDLER = "RESOURCE_HANDLER";
In any case, I suspect you're best off to try to hide all this in your
resource implementation rather than be tweaking GMF itself.
