mx.controls.Text: preventing scroll on select

A minor annoyance in Flex that I've lived with for many moons now is that even though I will provide enough vertical space to show all the text or htmlText in a Text Control, when a user attempts to select the text, often times, the text will scroll up, hiding the first line. The easiest fix is to set selectable='false', and in most cases this will do the trick. There are times however, when a client will demand that text remain selectable. And that same client will be the first to complain about the apparently unnecessary scrolling of text.

I played around with this, but seriously, the mx.controls.Text class really doesn't give one much to work with. On browsing through the sdk source, I discovered I'd probably have better luck working with the wrapped UITextField. In the end I tapped into the scroll event and the alwaysShowSelection attribute of the UITextField to get me where I needed to go.

It's been a long week so I'm just going to post up a link to the solution here, and the source code here.
