[flexcoders] HTTPService conversion to ArrayCollection problem

[netdeep]

This is really bizarre but I have some code that was working previously and now 
is no longer working. I 
am using a servlet to output information in the following format:

<system>
<data>
<name>Channel 1</name>
<id>Rep1</id>
</data>
</system>

But I am now getting a runtime error: Error #1034: Type Coercion failed: cannot 
convert 
mx.utils::[EMAIL PROTECTED] to mx.collections.ArrayCollection

Code:

public function initializeBrowser(evt:ResultEvent):void {
        var arr:ArrayCollection = evt.result.system.data;
}

<mx:HTTPService id="reportsList" result="initializeBrowser(event)" 
useProxy="false"
        method="GET" url="{dbURL}"/>
