[flexcoders] Lagging Panel title

[droponrcll]

Hi, all;

I have a component that extends Panel.  The panel title is bound to a private 
bindable variable that I set in commitProperties.  The title variable updates, 
but the titleTextField.text doesn't update, so the title always lags behind.

I haven't done Flex on a regular basis in a few months, so if someone can see 
what I'm doing wrong here, I'd appreciate it:
