      *  <code>persistNavigatorState</code> flag is set to <code>true</code>.

     * 
     *  <p>When the persistence object is being created, the application dispatches
     *  a cancelable <code>FlexEvent.APPLICATION_PERSISTING</code> event when the process
     *  begins and a <code>FlexEvent.APPLICATION_PERSIST</code> event when it completes.  
     *  If the <code>APPLICATION_PERSISTING</code> event is canceled, 
     *  the persistence object is not created.
     *  Similarly, when this information is being restored to the application, a cancelable
     *  <code>FlexEvent.APPLICATION_RESTORING</code> event is dispatched followed by a
     *  <code>FlexEvent.APPLICATION_RESTORE</code> event.  
     *  Canceling the <code>APPLICATION_RESTORING</code> event prevents the navigation 
     *  data from being restored.</p>
     * 
     *  <p>The <code>persistNavigatorState</code> flag must be set to <code>true</code> before

     *  and closes it if set to <code>false</code>.
