首先让我说我对Adobe Flex一无所知。这个应用程序是由承包商创建的，然后在内部带回来，这里的开发人员都不知道有关Flex的任何信息。我试图渲染一个简单的下拉列表，但收到错误＆＃34;访问未定义属性shipstatusArray＆＃34;。
以下是下拉列表的xml：
<s:GridColumn headerText = "Shipping Status">
<s:itemRenderer>
<fx:Component>
<s:GridItemRenderer >
<s:DropDownList id="myDDL" width="140" dataProvider="{shipstatusArray}" >
</s:DropDownList>
</s:GridItemRenderer>
</fx:Component>
</s:itemRenderer>
</s:GridColumn>
这是定义：
[Bindable]public var shipstatusArray:ArrayCollection = new ArrayCollection([{id:1, name:'In Progress'},
{id:2, name:'Completed'}]);
我不确定需要什么，所以这里是整个代码页：

您发布的代码段似乎缺少开始标记<fx:Script>。请添加。
为您的值添加双引号。
[Bindable]public var shipstatusArray:ArrayCollection = new ArrayCollection([{id:"1", name:"In Progress"}, {id:"2", name:"Completed"}]);
使用labelField指示您要显示的字段。
<s:DropDownList id="myDDL" width="140" dataProvider="{shipstatusArray}" labelField="name" />
您可以使用this link作为参考。
