List Control and XML data

Question

I am trying to display XML data from a HTTPReqeust in a list
control. Here's my mxml:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute" creationComplete="aircrafts.send()">
<mx:Script>
<![CDATA[
import mx.collections.XMLListCollection;
import mx.rpc.events.ResultEvent;
[Bindable]
private var aircraftDp:XMLList;
private function aircraftXMLHandler(event:ResultEvent):void
aircraftDp = event.result.aircraft;
]]>
</mx:Script>
<mx:HTTPService id="aircrafts"
url="
http://localhost:8080/flysafe/aircrafts"
result="aircraftXMLHandler(event)"
resultFormat="e4x"/>
<mx:List x="10" y="53"
dataProvider="{aircraftDp}"></mx:List>
</mx:Application>
The REST service returns the following XML document:
<aircrafts>
<aircraft id='0' label='Cessna' href='
http://localhost:8080/flysafe/aircrafts/0'/>
<aircraft id='1' label='Piper' href='
http://localhost:8080/flysafe/aircrafts/1'/>
</aircrafts>
The List control is empty. I cannot figure out how to get the
right connection between the data provider and the xml returned by
the HTTPRequest.

Answer 1

I figured it out. The data provider was set up correctly, but
I wasn't telling the listbox what to use for the label. Adding the
following attribute to the listbox fixed the problem.
labelField="@id"
