Because it is type safe. Instead of User u =
(User)session.get("_theUser"); you simply do User u =
session.getUser(). This makes it obvious what can be in your session
at any giving time, and refactoring etc will be easy.

If you want that, provide your own session and expose those methods
yourself. We don't provide it because we think it is bad programming
practice.

override newSession and return your session object there. The method
will be called by Wicket.

You could do that. Though it might be better if you made the contract
of having a user more explicit e.g. by requiring it (or it's id) as a
constructor argument in other pages or components. Your choice.

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())?
