    Error 2007 when dismissing alert with Yes No buttons

    Marvin-Martian Level 1

      Hi

       

      I have some Alert boxes that display the Yes / No buttons - I originally had this problem when dismissing the Alert - it would throw a 2007 error - "Parameter source must be non-null".

       

      Googling around revealed that this was a bug that could be overcome by explicitly specifying the default button in teh Alert.show call - I amended my code and all was well - for a week. Now the error is back again, even though the code still has the workaround.

       

      Typical call:

       

      Alert.show(msg, "Remove Contacts", Alert.YES | Alert.NO,
                  this, deleteContactConfirmationHandler, null, Alert.NO);

      Throws the error:

       

      TypeError: Error #2007: Parameter source must be non-null.

      I'm using Flex builder 3.0 (build 3.0. 2.214193)

       

      Does anyone know why this is still happening?

       

      Cheers
