    TitleWindow problem


      Hi everyone


      I'm using Flex Builder 4.5


      My project has:


      a main application: it calls a module

      a module: it call some components

      a component that has a botton. When I press the button the code is:

          var myPop: PopupCont= PopUpManager.createPopUp(this, PopupCont, true) as PopupCont;



      When I press the button I have this exception:

      TypeError: Error #1009: Cannot access a property or method of a null object reference.

          at components.Prova::prova/___prova_Button1_click()[D:\Flex4.5\APP\src\components\Prova\prov a.mxml:31]



      I tried to call my popup in the main application and it works fine.

      In this situation it works also the button in my component.


      I don't want to add the reference to my popup in main application

      How could I do?


      Thanks in advance
