flex2使用HTTPService得到xml数据绑定到datagrid

showlist.mxml:
<?xml version="1.0" encoding="utf-8"?>

<mx:HTTPService id="employeeSrv" showBusyCursor="true" url="employees.jsp">
<mx:request>
<deptId>{dept.selectedItem.data}</deptId>
</mx:request>
</mx:HTTPService>
<mx:TitleWindow title="HTTPService" horizontalAlign="center" height="299" width="662">
<mx:HBox horizontalAlign="center">
<mx:Label text="选择部门:"/>
<mx:ComboBox id="dept" width="150">
<mx:dataProvider>
<mx:Array>
<mx:Object label="工程部" data="ENG"/>
<mx:Object label="产品管理" data="PM"/>
<mx:Object label="市场部" data="MKT"/>
</mx:Array>
</mx:dataProvider>
</mx:ComboBox>
<mx:Button label="查询" click="employeeSrv.send();"/>
</mx:HBox>
<mx:HBox width="100%" height="211">
<mx:DataGrid dataProvider="{employeeSrv.lastResult.employees.employee}" width="100%" height="198">
<mx:columns>
<mx:Array>
<mx:DataGridColumn dataField="name" headerText="姓名"/>
<mx:DataGridColumn dataField="phone" headerText="电话"/>
<mx:DataGridColumn dataField="email" headerText="邮件"/>
</mx:Array>
</mx:columns>
</mx:DataGrid>
</mx:HBox>
</mx:TitleWindow>
</mx:Application>
