    Description

      Flash Builder 4.0.1
      Flex SDK 4.5.0.19786 + AIR SDK 2.6

      Import and run the attached FXP through the debug tool. When I type something into the ComboBox TextInput and press the Backspace key, the following error appears in the console:

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