          org.apache.turbine.modules.screens.error.InvalidState

public class InvalidState

extends Screen

Users will get this screen if the screen on their browser is in an invalid state. For example, if they hit "Back" or "Reload" and then try to submit old form data. If you want one of your screens to check for invalid state then add a hidden form field called "_session_access_counter" with the value currently stored in the session. The SessionValidator action will check to see if it is an old value and redirect you to this screen.
