code: public static void removeLongLivedPageFlow( String modulePath, HttpServletRequest request )
      {

docs: Remove a "long-lived" page flow from the session. Once it is created, a long-lived page flow
  is never removed from the session unless this method or {@link PageFlowController#remove} is
  called.  Navigating to another page flow hides the current long-lived controller, but does not
  remove it.
  @deprecated Use {@link #removeLongLivedPageFlow(String, HttpServletRequest, ServletContext)} instead.
