Confirmation Dialog Problem

Question

Hello!
I am facing a peculiar problem in the production system where in the confirmation dialog isn't working and the NullPointerException is getting thrown. For some reason the production server isn’t getting the handle for the event even though they are defined and the same piece of code is working fine in both Dev & QA.
Could someone look into the code and let me know what I can do to make it work.
    try
          String dialogTxt =     "Are you sure you want to ignore changes? ";
          IWDEventHandlerInfo eventIgnore               =     wdControllerAPI.getViewInfo().getViewController().findInEventHandlers("evtIgnoreChanges");
          IWDConfirmationDialog dialog               =     wdComponentAPI.getWindowManager().createConfirmationWindow(dialogTxt,eventIgnore,"Yes");
          IWDEventHandlerInfo eventIgnoreCancel     =     wdControllerAPI.getViewInfo().getViewController().findInEventHandlers("evtIgnoreCancel");
          dialog.addChoice(eventIgnoreCancel,"No");
          dialog.setWindowPosition(WDWindowPos.CENTER);
          dialog.setWindowSize(250,50);
          dialog.open();
    }catch(Exception ex)
         wdComponentAPI.getMessageManager().reportException("Error ignoring changes",true);
         ex.printStackTrace();
Thank you very much in advance.

Hi,
Use this code:
IWDControllerInfo controllerInfo =
        wdControllerAPI.getViewInfo().getViewController();
      String dialogText = "Are you sure you want to ignore changes?";
      IWDConfirmationDialog dialog =
        wdComponentAPI.getWindowManager().createConfirmationWindow(
          dialogText,
          controllerInfo.findInEventHandlers("evtIgnoreChanges"),
          "Yes");
      dialog.addChoice(
        controllerInfo.findInEventHandlers("evtIgnoreCancel"), "No");
      dialog.open();
check if you have created events with name evtIgnoreChanges & evtIgnoreCancel in your view controller.
