/**
 *	If Actions throw this exception from execute(), the dispatcher will show
 * the view corresponding to the chosen result.
 *
 * This is primarily useful for certain types of checking. For example, if an
 * action can only be executed if the client is logged in, he can have a method
 * "checkLogin", which checks the login status and throws ResultException if
 * not logged in. The view would then be the login screen, and "checkLogin" should
 * be called first in the action's execute() method.
