Flex 4 使用带有 XML 和项目渲染器的数据组时出现问题

我有一个带有自定义项目渲染器的数据组，当我将它从 http 服务绑定到 XML 时，它停止工作。

我的 XML：

<SDLIST>
<chartlist>
    <reportname>FACTORY STATUS</reportname>
    <reportimage>file:/D:/Work/RapidReport/Images/Charts/Vertical-Linear-Gauges.png</reportimage>
</chartlist>
<chartlist>
    <reportname>FACTORY STATUS</reportname>
    <reportimage>file:/D:/Work/RapidReport/Images/Charts/Vertical-Linear-Gauges.png</reportimage>
</chartlist>

然后我的数据组：

<s:DataGroup x="10" y="42" width="696" height="414" itemRenderer="myComponents.ChartListComp" dataProvider="{new XMLListCollection(XML(getSpeedDialList.lastResult).SDLIST.charlist)}">

我的Http服务：

<mx:HTTPService resultFormat="e4x" id="getSpeedDialList" url="{serverURL}/Reporting/GetSpeedDial.xml" useProxy="false" method="POST" fault="Alert.show('There has been an a problem with the connection.\nPlease check your internet connnection and try again.' + getSpeedDialList.url ,'Connection Error')" showBusyCursor="true"  >

我的组件使用：

{data.reportname}

我会很感激任何帮助，刚刚从flex 3升级，我不确定这是哪里的行为缺失。

预先感谢您的帮助。

<s:DataGroup x="10" y="42" width="696" height="414" itemRenderer="myComponents.ChartListComp" dataProvider="{new XMLListCollection(XML(getSpeedDialList.lastResult).SDLIST.charlist)}">

My Http Service:

<mx:HTTPService resultFormat="e4x" id="getSpeedDialList" url="{serverURL}/Reporting/GetSpeedDial.xml" useProxy="false" method="POST" fault="Alert.show('There has been an a problem with the connection.\nPlease check your internet connnection and try again.' + getSpeedDialList.url ,'Connection Error')" showBusyCursor="true"  >

My Component uses:

看起来是您的根标记，在这种情况下，getSpeedDialList.lastResult 已经指向该节点 - 您不应该在 e4x 查询中明确提及这一点。

<s:DataGroup x="10" y="42" width="696" height="414" 
    itemRenderer="myComponents.ChartListComp" 
    dataProvider="{getSpeedDialList.lastResult.charlist}">

而且您确实是从创建完成或类似的地方调用 getSpeedDialList.send() ，不是吗？

Looks like <SDLIST> is your root tag, in that case, getSpeedDialList.lastResult already points to that node - you shouldn't explicitly mention that in the e4x query.

<s:DataGroup x="10" y="42" width="696" height="414" 
    itemRenderer="myComponents.ChartListComp" 
    dataProvider="{getSpeedDialList.lastResult.charlist}">

And you're indeed calling getSpeedDialList.send() from creation-complete or some place like that, aren't you?
