Fernando's right. Your field curruser starts out as an ASO but if you
reassign it (eg. curruser = u) then it becomes something else which is
not an ASO.
Your code looks like it's a mod of JumpStart, but JumpStart actually
does the same kind of thing Fernando's saying:
@ApplicationState
private Visit _visit;
private boolean _visitExists;
<snipped>
User user = getSecurityFinderService().authenticateUser(_loginId,
_password);
// Store the user in the Visit
_visit.noteLogIn(user);
and Visit then sets its fields based on the user. That way it remains
an ASO.
public void noteLogIn(User user) {
_loggedIn = true;
_myUserId = user.getId();
_myLoginId = user.getLoginId();
}

Also, i thought you were to think of an ASO almost as a singleton or
a service. Tapestry will create it for you on first access. I
didn't know you could set it. Even if I'm wrong, using this design
pattern might clean things up a little.
So you should use another class to contain a reference to the
current active user, call it "UserContainer".
@AplicationState
private UserContainer currUser;
and it would have methods like:
currUser.hasUser()
currUser.setUser(User user)
currUser.getUser()
or whatever you like.

Natia,
I think there is a mistake in your code :
private User currUser ;
private boolean userExists ;
I dont think T5 will link userExists and currUser, currUser should
be named user, or userExists currUserExists (please correct me if
I'm wrong).
That said, what do you mean "I cant access currUser", do you mean
that the ASO is null in other classes that want to read it ? Or do
you mean that userExists is always false (which is normal, see
above).
