LOL. "How about the other way around, how can I access a variable in my main mxml from my class package?"
Well, the real answer is you shouldn't do it. You really don't want to build dependencies between your classes (unless there's a really good reason) or between a class and your application. A really bad way to do what you're asking: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; layout="absolute" creationComplete="doIt()"> <mx:Script> <![CDATA[ var s:String="ABC"; function doIt():void { Application.application.s+="..DEF"; txtFld.text=s; } ]]> </mx:Script> <mx:Text id="txtFld" text="UNSET" /> </mx:Application> The Application class has a static attribute application that refers to the application scope. Please don't use it without a really good reason. Really speaking most people issue events inter-class communication (without building inter-dependencies), or would pass the variable as a parameter. If the variable being passed is an object reference, you can still update the value when it's passed as a parameter. Other techniques people use - static class variables - accessible without instance declaration. I think there's something else I've forgotten. It's late!
