I also got the same problem when I run the example application, registration. It is likely becasue the Seam component, ApplicationUser(in your case), doesn't get instantiated. that's why the property value cannot get set. You can try to put the following message in your jsp for little bit more detail <h:messages showDetail="true"/> I have posted this problem, hopefully, the jboss guy cannot tell me what is going on. Or if you know why, please let me know too. Thanks Benson View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4077158#...
