Code working in Flash but not Flex...why?

I have this code creates a function at runtime (yes, this IS needed):

PHP Code:

---

var createdFunction = function():void {
    trace("Function Created");
}

createdFunction(); 


---

Putting in in to the actions panel in Flash CS4 and compiling works fine, tracing the message "Function Created"...

However, the Flex compiler gives me this

Quote:

---

Error: Call to a possibly undefined method createdFunction.
createdFunction();
Build halted with errors (fcsh).

I was able to compile this with the flex 4 compiler with only a warning about createdFunction being untyped (why wouldn't you give it a type?). Typing it as * or Function results in exactly what you would expect.

Code:

---

package
{
        import flash.display.Sprite;
        import flash.events.Event;
       
        /**
        * ...
        * @author srs
        */
        public class Main extends Sprite
        {
               
                public function Main():void
                {
                        if (stage) init();
                        else addEventListener(Event.ADDED_TO_STAGE, init);
                }
               
                private function init(e:Event = null):void
                {
                        removeEventListener(Event.ADDED_TO_STAGE, init);
                        // entry point
                        var createdFunction:Function = function():void {
                                trace("Function Created");
                        }
                        createdFunction();
                }
               
        }
       
}

Don't know much about types since I'm quite new at AS3 (It's so different to the old AS2)...but your code works perfect...thanks!
