I have a Flex App, that is working nice but I want to be able
to set the height of the primary viewstack to the height of the
content of the textarea within the viewstack. I want the Flex App
to only ever have one vertical scrollbar so it behaves like a
'normal' web page. I assume I will need to listen to the resize
event of the App as well as some event on the textarea for when its
data has loaded.
