Hi Per, thank you very much for your answers.
Yes, that was it. I added WiaSession.get().bind(); to my LoginPanel and
now it works as it should :-)
Every time when the LoginPanel is showed, the session will be binded.
Phu, I was trying to fix that over three days ^^

René

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.

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.)

LoginPanel.java:
public class LoginPanel extends Panel {
public LoginPanel(String id) {
super(id);
add(new LoginForm("login"));
}
private class LoginForm extends StatelessForm {
private String username;
private String password;
public LoginForm(String id) {
super(id);
setModel(new CompoundPropertyModel(this));
add(new TextField("username"));
add(new PasswordTextField("password"));
}
@Override
public final void onSubmit() {
if (tryToLogIn()) {
if (!continueToOriginalDestination()) {
setResponsePage(getApplication().getHomePage());
}
}
}
private boolean tryToLogIn() {
if (username != null&& password != null) {
User user = Database.findUser(username);
if (user != null) {
if (user.comparePasswords(password)) {
WiaSession.get().setUser(user);
return true;
}
}
}
return false;
}
}
}
WiaSession.java:
public final class WiaSession extends WebSession {
private User user;
public WiaSession(Request request) {
super(request);
}
public static WiaSession get() {
return (WiaSession) Session.get();
}
public static boolean isLoggedIn() {
return WiaSession.get().isAuthenticated();
}
public boolean isAuthenticated() {
return (user != null);
}
public final synchronized User getUser() {
return user;
}
public final synchronized void setUser(User user) {
this.user = user;
}
}
WicketApplication.java, newSession overwritten:
@Override
public final Session newSession(Request request, Response
response) {
return new WiaSession(request);
}
