Using HTTPService as data provider for mx:ComboBox

Question

Hello all,
I'm trying to use an HTTPService as a data provider for an
mx:ComboBox. Here's how I have my HTTPService configured:
<mx:HTTPService id="listStates" url="
http://localhost:3006/state/list"
useProxy="false" method="GET" />
I have a Rails backend setup and talking to a database on my
local machine. I have a list of states in a table in my database,
and the table has two columns: id and name. When I go to
localhost:3006/state/list in my browser, I get the following XML:
<states>
<state>
<id type="integer">1</id>
<name>New Mexico</name>
</state>
<state>
<id type="integer">2</id>
<name>Arizona</name>
</state>
</states>
I have my mx:ComboBox set up like so:
<mx:ComboBox width="199" id="state" dataProvider="{
listStates.lastResult.states.state }" />
However, when I browse to my .swf file, my state combo box
shows [object Object] twice in the drop-down list. Anyone have any
idea why it's not parsing the data correctly? Any suggestions on
how to make it work?
Thanks in advance!!! -- BTR

Alright I worked one out for you. Let me know if you have any
questions.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute"
creationComplete="dropDown.send()">
<mx:Script>
<![CDATA[
import mx.rpc.events.ResultEvent;
import mx.collections.ArrayCollection;
import mx.controls.Alert;
public var dropArr:XML;
public function get_drop_down(e:ResultEvent):void{
dropArr = e.result as XML;
state.dataProvider = dropArr.state;
state.labelField = "name";
state.data = "id";
]]>
</mx:Script>
<mx:HTTPService id="dropDown" useProxy="false"
url="
http://localhost/dropDown.php"
resultFormat="e4x"
result="get_drop_down(event)" />
<mx:ComboBox width="199" id="state" />
</mx:Application>
