Hi,
I'm not sure, whether this is the right forum or the EMF forum is the better choice. But I thought, this could be more of an Eclipse 4 topic.
I'm creating a Eclipse 4 RCP that uses EMF resources as input. Now I want to implement undo/redo functionality. In Eclipse 3.x the EMF generated editor used an EditingDomain that includes a CommandStack. I thought maybe I could use this EditingDomain in the Eclipse 4 RCP, too. So I created the EditingDomain like in the EMF Editor:
adapterFactory = new ComposedAdapterFactory(
ComposedAdapterFactory.Descriptor.Registry.INSTANCE);
adapterFactory
.addAdapterFactory(new ResourceItemProviderAdapterFactory());
adapterFactory
.addAdapterFactory(new IdentifiableItemProviderAdapterFactory());
adapterFactory
.addAdapterFactory(new ReflectiveItemProviderAdapterFactory());
BasicCommandStack commandStack = new BasicCommandStack();
commandStack.addCommandStackListener(new CommandStackListener() {
@Override
public void commandStackChanged(EventObject event) {
eventBroker.post(UIEvents.Dirtyable.DIRTY, dirtyable);
}
});
editingDomain = new AdapterFactoryEditingDomain(adapterFactory,
commandStack, new HashMap<Resource, Boolean>());
editingDomain.getResourceSet().getResources().add(resource);
Unfortunately the CommandStack is always empty. Does anabody have an idea what else I have to do, to get the CommandStack filled, if an action on the resource is permormed?
Best regards
Bastian
