Sounds like you're running into the 'one-frame-delay-thing' that is known to most Flash users.
Try using callLater() and see if that fixes it, or use one of the events, such as 'add', 'added', 'creationComplete', 'updateComplete', 'resize'.. Not sure which one will be triggered at the right moment, so you'll have to test it. regards, Muzak ----- Original Message ----- From: "munkydung" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Saturday, September 02, 2006 1:08 AM Subject: [flexcoders] UIComponent.width is always 0 Well, not always...
