Description

Steps to reproduce:
1. Launch LoaderTest.swf (I could not attach it because it only allowed 3 files to be attached).
2. Click on the combo box or the show alert button to launch an Alert
3. A system error occurs

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

at Child/___Child_Button1_click()[/Users/jbezuidenhout/Documents/Flex Builder 3/enqpro/src/Child.mxml:19]

This is similar to SDK-19228 that was marked as fixed.

Expected Results:
Combo box should be selectable, the Alert should pop up

Workaround (if any):
None
