Hi Paul, MX components should normally not be a problem. Are you sure you have the mx namespace defined?
Like this e.g. in a spark VGroup that uses mx components (the xmlns:mx part): <?xml version="1.0" encoding="utf-8"?> <s:VGroup xmlns:fx="http://ns.adobe.com/mxml/2009"; xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" Cheers Paulus -- Sent from: http://apache-flex-users.2333346.n4.nabble.com/
