The query is only checking for existing users with the same username. This should come back with an empty result set if the username is unique. I believe that Seam has created and populated the User object with parameters from the JSF page prior to the call to my Register.register(). My question is how do I get the Account object instantiated with the User object in Seam? Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4113101#...
