[seam-dev] How to "clear" something from a context

[Pete Muir]

This is something that was quite commonly needed in Seam, in part due  
to the use of outjection. As 299 doesn't support outjection, you need  
to use the manager pattern:

@SessionScoped
public class Login {

    public User user;

    public Login(@New User user) {
       // Initialize with an empty, new, user - the "not logged in" user
       this.user = user;
    }

    public void login(User user) {
       // Log in a real user
       this.user = user;
    }

    @Produces @LoggedIn @RequestScoped
    public User getCurrentUser() {
       return user;
    }

}

This is much cleaner :-)
