I tested the code before, without the validateNow on the the text instance, so that wasn't bothering me.
When you call validateNow() on the application I guess you get the same result as with callLater() because validateNow() takes 'a frame' to execute, thus the code after that (the debug text) is delayed/executed later. Hope that makes sense.. I understand what you mean by things being different in Flex, but I think that's not really relevant here. The thing is that text properties do not have the 'correct' value immediatly when added to the display list through actionscript. regards, Muzak ----- Original Message ----- From: "Michael Schmalle" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Saturday, September 02, 2006 6:54 AM Subject: Re: [flexcoders] UIComponent.width is always 0 >> Nope, it doesn't.
