调用的方法Embed可能未定义

这个问题好奇怪，一般来说，调用的方法或属性未定义，基本上都是因为某个对象没有被初始化。

出问题的代码如下：

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init()">
<mx:Script>
    <![CDATA[
        import mx.events.ListEvent;

        [Bindable]
        private var dp:Array = [
                                {name:"John Smith", position: "developer"},{name:"Ellen Smith", position: "manager"},
                                {name:"Hames Smith", position: "accountant"},{name:"Jane Smith", position: "designer"}
                                ]                  //解决方法：后面加个分号；就可以了，百思不得其解！

        [Embed(source="image/1.jpg")]
        public var managerIcon:Class;

        [Embed(source="image/2.jpg")]
        private var designerIcon:Class;

        [Embed(source="image/3.jpg")]
        private var accountantIcon:Class;

        [Embed(source="image/4.jpg")]
        private var developerIcon:Class;

        private function setIcon(value:*):Class
        {
            if(value.position != null)
            {
                switch(value.position)
                {
                    case "manager":
                        return managerIcon;
                        break;
                    case "developer":
                        return developerIcon;
                        break;
                    case "accountant":
                        return accountantIcon;
                        break;
                    case "designer":
                        return designerIcon;
                        break;
                }
            }
            return null;
        }
    ]]>
