Hmm, I would have suggested that an IListener on the container is preferrable over an IElementProcessor. In both cases you should check isActive() on the added container element (your repository) and if it's not yet active add another listener (LifecycleEventAdapter) to that element and postpone your processing. If yu submit a bugzilla I can abstract this pattern in a new ActivationAdapter class because this looks like a common use case.

Okay, I will try to add a listener directly to the container. Where do I that? Or can it be done declaratively?

Only programmatically I fear:
IPluginContainer.INSTANCE.addListener(new IListener() {...});
I like the idea of being able to do it declaratively, though. Can you file a bugzilla to remind me?
