Classe AS3 con Flex

[lucavalentino]

Ho creato questa classe

package 
{
	public class Greeter
	{

		public function sayHello (n:String):String
		{
			var greeting:String;
			greeting="Hello World, "+n;
			return greeting;
		}
	}
}

In Flex questo

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
	xmlns:src="Greeter">
	<mx:Text text="Text" height="100"  id="mainText" name="mainText" verticalCenter="0" enabled="true" width="300" horizontalCenter="-56">
	<mx:Script>
		<![CDATA[
		public function init():void
		{
			var myGreeter:Greeter = new Greeter();
			mainText.text = myGreeter.sayHello("Luca");
		}
		]]>
	</mx:Script>
	</mx:Text>
	</mx:Application>

Vorrei he nel componente text venga la scritta Hello World , Luca sparendo quella di default Text.

Grazie
