This seems to work correctly from my Windows XP machine, but fails on my Windows Vista machine.

It makes me wonder if somehow the garbage collection button just isn't working right.

Behavior is the same on Flex 2.01 and Flex 3 build 429, on any platform Windows XP, Windows Vista, Mac, and Linux. The changeFH() function sets the form heading label to null which produces "Error #1009 Cannot access a property or method of a null object reference". Seems logical to me that this error is to be expected. Closing as not a bug.

The windows vista comment was applied to the wrong issue. Please ignore that comment.

However, I don't see how you can possibly say this is not a bug when you can say

label.text = null
textInput.text = null
formItem.text = null

and they all handle that exception, but FormHeading is the only one that fails.

BTW, just because it also failed in Flex 2.01, doesn't make it right.

Not a bug? setting the text to null should throw a run time error? that seems just wrong. it would be much much better if it through a compile time error instead. if its not legal syntax, shouldnt the compiler catch that?
