     /**
36 |  |
      * Users will get this screen if the screen on their browser is in an
37 |  |
      * invalid state.  For example, if they hit "Back" or "Reload" and
38 |  |
      * then try to submit old form data.
39 |  |
      *
40 |  |
      * If you want one of your screens to check for invalid state
41 |  |
      * then add a hidden form field called "_session_access_counter"
42 |  |
      * with the value currently stored in the session.  The
43 |  |
      * SessionValidator action will check to see if it is an old
44 |  |
      * value and redirect you to this screen.
