java 4: MySession mySession = (MySession)Session.get();
java5: MySession mySession = MySession.get();
(add a get() method on your MySession object)

So you're saying that I'm supposed to...
class MySession extends WebSession {
private User selectedUser;
public get/setUser() { ... }
}
And wicket will keep a single instance of this class in memory at all
times, so as not to lose my selected value? And how do I access my custom
version of the Session, from a Page, Component, etc,
((MySession)getSession())?
