让我先说我对Adobe Flex一无所知。这个应用程序是由一个承包商创建的，然后带回内部，这里的开发人员都不知道Flex。我试图呈现一个简单的下拉列表，但收到错误“访问未定义的属性shipstatusArray”。
下面是下拉列表的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>

定义如下：

[Bindable]public var shipstatusArray:ArrayCollection = new ArrayCollection([{id:1, name:'In Progress'},
            {id:2, name:'Completed'}]);

我不确定需要什么，所以下面是完整的代码页：

任何帮助都是非常感谢！

您发布的代码片段似乎缺少开始标记<fx:Script>。请添加该标记。
为值添加双引号。

[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。
