1、错误描写叙述

此行的多个标记:
-workId
-1067: spark.components:NavigatorContent 类型值的隐式强制指令的目标是非相关类型 String。

<fx:Script>
		<![CDATA[
			import mx.controls.Alert;
			
			protected function search_clickHandler(event:MouseEvent):void
			{
				var teacher:Teacher = new Teacher();
				var workId:String = teacher.workId;
				Alert.show(workId);
			}
		]]>
	</fx:Script>
