Re: Barracuda: Automatic creation of ListenerFactories?

Hi Ron,

The thread I was referring to below has the subject "Event 'hierarchy' 
(events.xml) question".

http://barracuda.enhydra.org/project/mailingLists/barracuda/msg05453.html

 From Christian description, that would just make the registration of 
events automatic, but I'm not sure I see how they'd get matched up with the 
handlers?  Christian?
