Hi, try to expose the text that should be displayed in the SystemMessage component as a public member and let the Label bind to this member, i.e. <?xml version="1.0" encoding="utf-8"?> <mx:Canvas xmlns:mx="http://www.macromedia.com/2005/mxml" xmlns="*"> <mx:Script> <![CDATA[ [Bindable] public var message:String; ]]> <mx:Script> <mx:Label id="TheMessage" text="{message}"/> </mx:Canvas>
Later you do private function addLabel():Void { currentState="LabelAdded"; TheSystemMessage.message = "I have been added"; } Dirk. ________________________________ From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Ralf Rottmann Sent: Thursday, December 08, 2005 2:34 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Part 2: Issues with State and Component creation (Flex 2.0 Alpha) Here is some code which illustrates the issue: 1. The Component (File SystemMessage.mxml): <?xml version="1.0" encoding="utf-8"?> <mx:Canvas xmlns:mx="http://www.macromedia.com/2005/mxml" xmlns="*"> <mx:Label id="TheMessage"/> </mx:Canvas> 2.

If you dismiss the error subsequent clicks work.
