I understand what you're proposing, but I don't really see the benefit of it yet. 1. Why can't these routing expressions be defined with the CBR action Vs on the incoming message? What use case would not be supported? 2. If the invoking client is specifying the CBR expression to be used by the CBR, then does it not make the CBR step a bit redundant... why can't the client effectively perform the CBR? 3. From a logic standpoint, it seems to me that the appropriate place for the CBR rules is in/with the CBR action. 4. Security?? Martin, would you be OK with putting this one on the back boiler for now? We can always add it later. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4256675#...
