Subject exist return true before event comes in
Date Tue, 04 Aug 2009 02:30:45 GMT

I'm running into following problem writing a fasade for Zk Client (http://github.com/joa23/zkclient/


1.) Subscribe a watch via exist(path, true) for a path.
2.) Create a persistent node.
3.) Call exist and it returns true
4.) Zookeeper sends a NodeCreated event.

I would expect that the client would get the NodeCreated event before  
exist returns true.
Does anyone has a idea of a pattern that secures that exist return  
false, before the event is triggered?
