[infinispan-dev] singleton @Listeners

This is a problem that pops up constantly: User:      "I add a listener to my distributed/replicated cache but this gets invoked numOwners times - can I make that to be invoked only once cluster wise?" Developer: "Yes, you can! You have to do that and that..." What about a "singleton" attribute on the Listener? Would make the reply shorter: Developer: "Use @Listener(singleton=true)" Cheers, Mircea
