Re: [ND] Can't execute RemoveUserSession in ND4 on logout

[DAMIAN_O\'CONNOR]

     Hi Aby,
     
     Thanks for the reply. I suppose I should have explained that the user 
     has the option to return to the project (via another button) and 
     therefore a removeUserSession() in the this_OnBeforeHTMLOutputEvent 
     probably isn't applicable.
     
     Our original code was: (still on ND3 event model)
     
     public int onContinueWebEvent( String args[] ) 
     {
     
        // Terminate the user session and jump to the HP connect 
        // Logon screen.
     
           int command = PROCEED_WITH_BUILTIN_HANDLING;
     
           CSpButton myHelp = (CSpButton) getDisplayField ("btExit");       
           myHelp.setActionType(CSpCommand.GO_TO_EXTERNAL_URL_ACTION_TYPE); 
     
           try
           {
     
              String HPLogoutURL = 
                  CSpider.getUserSessionObject("HPLogoutURL").toString(); 
              myHelp.setExternalURL (new URL(HPLogoutURL)); 
           }
           catch (MalformedURLException ex)
           {
              CSpLog.send(this, CSpLog.ERROR, "pgLogOut, 
                   MalformedURLException for Logout");
           }
     
           myHelp.setSendSessionToExternalURL (true); 
           command = doAction(args);
     
           try
           {
              CSpider.removeUserSession();
           }
           catch (Exception ex)
           {
              CSpLog.exception(this, "removeSessionId", ex);
           }
     
           return(command);
     
     }
     //]]SPIDER_EVENT<onContinueWebEvent>
     
     
     We changed the CSpider.removeUserSession() with the following two 
     commands. It seems to work:
     
     CSpSession currSession = CSpider.getUserSession();
     currSession.removeAll();

     The concern I have is is this the correct way to clean up after ourselves!
     
     Thanks,
        Damian

Damian,
     
I would be a little surprised if removeUserSession() fails in the 
this_OnBeforeHTMLOutputEvent. Could you show us your code?
     
     
Aby
