[flexcoders] Error #1034: Type Coercion failed

[rdeijkers]

I'm trying to fill a Tile with the contents of an xml file. This is my
mxml code:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
layout="absolute" width="100%" height="100%" backgroundAlpha="0"
applicationComplete="srv.send();" horizontalScrollPolicy="off"
verticalScrollPolicy="off">
<mx:Script>
        <![CDATA[
                private function xmlLoaded():void {
            categorienAC = srv.lastResult.categorien.categorie;
            }   
        ]]>
</mx:Script>

<mx:Model id="categorienAC"/>
<mx:HTTPService id="srv" url="categorien.xml" useProxy="false"
result="xmlLoaded();" />
        <mx:Tile label="categorienTile" width="945" height="100%"
backgroundColor="#FFFFFF">
                <mx:Repeater id="list" dataProvider="{categorienAC}">
                        <mx:VBox backgroundColor="#000000">
                                <mx:Image source="{list.currentItem.foto}" 
width="75" height="70"/>
                                <mx:Label text="{list.currentItem.naam}"/>
                        </mx:VBox>
                </mx:Repeater>
        </mx:Tile>
</mx:Application>

My XML looks like this:

<categorien>
        <categorie id="19">
                <naam></naam>
                <omschrijving>test</omschrijving>
                <foto></foto>
        </categorie>    <categorie id="1">
                <naam>Arizona</naam>

                <omschrijving>test</omschrijving>
                <foto></foto>
        </categorie>    <categorie id="36">
                <naam>ARIZONA / GREY</naam>
                <omschrijving></omschrijving>
                <foto></foto>
        </categorie>    <categorie id="20">

                <naam>Atrium</naam>
                <omschrijving>test</omschrijving>
                <foto></foto>
        </categorie>    <categorie id="59">
                <naam>Avant Garde</naam>
                <omschrijving>test</omschrijving>
                <foto></foto>

        </categorie>
</categorien>

I'm receiving the following error when I try to execute my code :

TypeError: Error #1034: Type Coercion failed: cannot convert
mx.collections::[EMAIL PROTECTED] to mx.utils.ObjectProxy.
        at categorie/categorie::xmlLoaded()[Z:\project\categorie.mxml:6]

Anybody an idea what's going wrong ?

Anyhelp would be greatly appreciated.

Thanks

Regards
