非可视化组件（类）写的mxml中

执行顺序：构造方法-----》initialized方法,document和id的值，由flex框架提供

package core
{
	import mx.controls.Alert;
	import mx.core.IMXMLObject;

	public class ImxmlSupport implements IMXMLObject
	{
		private var document:Object;
		private var id:String;
		public function ImxmlSupport()
		{
//			mx.controls.Alert.show("普通非可视化类写到mxml中");//这不弹出对话框，debug也不能运行，不知道调用了没有
			trace("construct");//构造方法
		}

		public function initialized(document:Object, id:String):void
		{
			this.document=document;
			this.id=id;
			trace("初始化");
		}
		public function test(){
			mx.controls.Alert.show("普通非可视化类写到mxml中");
		}
		
	}
}
