> We go off into an infinite loop. Since Pinger doesn't exist, it is created and placed in the session scoped beanstore, which creates a session and fires off the observer. I'm not sure why the session isn't considered created at this point. This is bordering on feature since I think the result would be the same if servlet listeners would be used. Perhaps this could be worked around int the event bridge somehow so that the firing would be prevented if we're already handling the session created event...
