hmm that's odd... i'm coding a project right now and that's what i use... but i don't import everything (*)... hehe anyway, if you want typecasting, i usually do something like this:
var str:String = TextInput(HBox(vbox.getChildAt(i)).getChildAt(1)).text; let me know if it's not still working and i'll try to figure it out :) -Lee ----- Original Message ---- From: hoytlee2000 <[EMAIL PROTECTED]> To: [email protected] Sent: Wednesday, April 23, 2008 3:04:29 PM Subject: [flexcoders] Re: how do I loop thru dynamically created UI components? Hello Lee, Yes I did, if you mean by using the statement import mx.containers.*; I think the problem is that the getChildAt() method returns a DisplayObject, but I don't know how to cast it as an HBox or any other UIComponent. The DisplayObject doesn't even have a getChildAt() method. If I could figure out how to cast the returned DisplayObject as a particular UI component that would be great.
