I'd say because user.getState() returns null. Right? On 9/12/06, Michael Wölm <[EMAIL PROTECTED]> wrote:
Hi, Sadly, nobody have helped me with my problem. I dont know why. Am I too noob or is my question incomprehensible? I would be pleased, if anybody could give me an advice for my problem.

September 2006 16:13 An: 'Tapestry users' Betreff: Question: Can not get access to object fields (Null Pointer Exception) Hi, I hope anybody could explain me why I get a Null Pointer Exception, if I want to get access to a field of an object. My method is similar to the eshop-project of the book "Enjoying web dev with Tapestry". I tried to change the Listener-method onLogin as follows: public void onLogin(IRequestCycle cycle) { try { User user = Users.getKnownUsers ().getUser(email,password); getUser().copyFrom(user); if (user.getState().equals("admin")) cycle.activate("Admin_Konsole"); else cycle.activate("User_Konsole"); } catch (AuthenticationException e) { ValidationDelegate delegate = getDelegate(); delegate.setFormComponent(null); delegate.record("Login failed", null); } } Now I get an exception at point (user.getState().equals("admin")). But why? user was set to the login-user two lines before? Why I can't get the field: private String state which I have set in User.class: private String state; public String getState() { return this.state; } Thx ahead!
