[flexcoders] Populate TileList w/ data from XML file?

[daddyo_buckeye]

I'm trying to populate a TileList with data from an XML file. Any help 
is greatly appreciated.

Here's the data from the XML file:

<?xml version="1.0" encoding="iso-8859-1"?>
<uniforms>
        <patternGroup>
        <groupID>kj02</groupID>
        <sport>Basketball</sport>
        <groupStyle>Basketball Uniform</groupStyle>
        <thumbnail>assets/basketball/thumbnailsPNG/kj02.png</thumbnail>
        </patternGroup>
</uniforms>


Here's the code for the application file:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; 
layout="absolute" creationComplete="uniData.send()">

<mx:Script>
        <![CDATA[
        [Bindable]
        private var uniXML:XMLList;
                        
        private function uniHandler(evt:ResultEvent):void {
        uniXML=evt.result.patternGroup;
        }
        ]]>
</mx:Script>

<mx:HTTPService id="uniData" url="assets/uniforms.xml" 
result="uniHandler(event)" resultFormat="e4x"  />

<mx:TileList dataProvider="{uniXML}" labelField="groupID" 
iconField="thumbnail" width="400" height="400" />

</mx:Application>

What am I missing here?

thanks.
