StatelessForm: Cannot login

2012-02-09 Thread rene 
Hello,

I have a strange problem with StatelessForms in combination with login in:
On my MainPage are two stateless forms. One for registration and one for the
login (registration isn't implemented yet). When I try to log in, Wicket
creates a new User() and saves it in the Session (I made this like it's
explained in Wicket in Action). A System.out.print(user created) in the
constructor of User confirms that. Everything seems to be ok. But when the
main page reloads, I am still logged out. 
And: When I change from StatelessForm to Form, everything works perfectly.
Something else might be important: When I request a page that requries
authorization and I'm not logged in, i'm being redirected to /login. There
is the same LoginPanel (with StatelessForm) as on the main page - and the
login works! But when I directly open /login it's the same as on the main
page and I can't login.
I also noticed that the login works (with StatelessForm) when I open a page
that requires authorization, then press the back button (back to main page)
and there try to log in.

The question is now, what am I doing worng? I can't find the problem in my
code, I have been trying a lot to find out what's worng but everything seems
to be correct. I couldn't find anything in the mailing list / on the web, I
searched a lot.

At the end I attached code from LoginPanel.java, WiaSession.java and
WicketApplication.java.

Thank you very much for your help!
(And sorry if there are one or two missspelled words - I don't speak english
natively.)

Re: StatelessForm: Cannot login

2012-02-09 Thread Per Newgro 
If i understood your usecase correctly you're app is still stateless if 
you logged in.
Afaik no session is created for stateless pages. So after you've logged 
in the session
is away for your next page. And then the user is away to. You could 
debug it by print the

hashcode of getSession() in the page.

Cheers
