Setting a abstract variable does not work

[Alex2222 <ma...@tapestryforums.com>]

Hi! 
I am using Tapestry 4.0 with Spring 1.2.6 an got a problem with my Login procedure. I want to redirect my user after logging in to the previous requested, protected page. My protected pages are inherited from a ProtectedPage with a PageValidateListener:

-----
public void pageValidate(PageEvent event) {
  Login login = (Login) getRequestCycle().getPage("Login");
  login.setCallback(new PageCallback(this));
  throw new PageRedirectException(login);
}
-----

Login.java:
-----
public abstract void setCallback(ICallback value);
public abstract ICallback getCallback();
public void onLogin() {
  log.debug("callback:"+ getCallback());
}
-----

The logfile says "callback: null", but if I call login.getCallback from the listener method it has a value. How do I say Tapestry/Spring to persist my Callback? Is there another way to solve this problem?


Alex.

Are you sure you have mark the callback property as persistent?
