Hi all, Just after you success register a new user in appfuse(signup.html), "current user" at the windows's middle below area will show User object's "username" property. If you go to userforms.html and save user information again, it will show User object's "firstname" plus "lastname" property. It seems that the object have changed. If you call "User user = (User) SecurityContextHolder.getContext().getAuthentication().getPrincipal();" without step userforms.html, you will got a ClassCastException.
