Using your own ResourceSet with an EditingDomain [message #525199]

I have a case where I need to use my own ResourceSet with the generated
editor. The EditingDomain API supports this just fine, but you quickly
find out that when you modify a property, the editor never goes dirty.
It turns out that the item providers get access to the EditingDomain
through the AdapterFactoryEditingDomainResourceSet which does not exist
when you use your own ResourceSet. I've hacked around this problem as
follows:

editingDomain.getResourceSet().eAdapters().add(new EditingDomainAdapter());

private class EditingDomainAdapter implements Adapter, IEditingDomainProvider
{
@Override
public EditingDomain getEditingDomain()
{
return RuntimeEditor.this.getEditingDomain();
}

@Override
public void notifyChanged(Notification notification)
{
}

@Override
public Notifier getTarget()
{
return null;
}

@Override
public void setTarget(Notifier newTarget)
{
}

@Override
public boolean isAdapterForType(Object type)
{
if(type == IEditingDomainProvider.class)
return true;

return false;
}
}

Is there any better way to deal with this problem?

Bryan,

That's the right way. Extend your ResourceSetImpl to implement that
interface directly. Or extend AdapterImpl to write less methods.
