[AS3] Limiting a fl.Controls.TextInput to allow only Numbers?

[ColinDiam]

I have a formthat contain a Few TextInputs. The thing is I only want the user to be able to enter Numbers into the TextInputs so I can then parse them as integers. Is there anyway to do this so the user can enter say "123" but not "asd"?

myInput.restrict = "0-9";

That will allow as input only the digits 0 through 9, and no spaces or any other characters.
