Hi, I followed the example application, registration in JBOSS Seam. Unfortunately, it doesn't work. Environment : JBOSS Seam : 1.2.1 GA MyFaces 1.1.4 JBOSS AS : 4.0.5 GA the URL : http://localhost:8080/seam-registration/register.seam can be accessed. After entering the 3 parameters and hit register button, 3 error message was displayed as follows : * Conversion Error "_idJsp2": Error during model data update. * Conversion Error "_idJsp3": Error during model data update. * Conversion Error "_idJsp4": Error during model data update. And I finally discovered that the Seam component, user, is not instantiated, that's why the property value of user cannot get set. But the reason is why the user Seam component cannot get instantiated? If you guys have any idea, please let me know. This issue really makes piss me off. thanks Benson View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4077152#...
