HTTPService Issue returning GeoCode results to DataGrid

I am creating a Flex3 app to return some results from the Google Geocoding API.

I am using the HTTPService Events sample from TourDeFlex as a reference guide to mimic.

For now, I have hardcoded the response from Google to use this XML response: maps.googleapis.com/maps/api/geocode/xml?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&sensor=false

Network Monitor suggests that I am getting a valid response from the XML, but I imagine I have not referenced it correctly for populating my DataGrid?

I have screencasted the issue here.

Here is a stripped down version of my code:

private function resultHandler(event:ResultEvent):void
        {
        results = event.re开发者_开发问答sult.GeocodeResponse.result;
        }

        private function faultHandler(event:FaultEvent):void
        {
        Alert.show(event.fault.faultDetail, "Error");
        }           

    ]]>
</mx:Script>

<mx:HTTPService id="srv" 
            url="http://maps.googleapis.com/maps/api/geocode/xml?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&amp;sensor=false"
        result="resultHandler(event)"
            fault="faultHandler(event)"/>

<mx:TitleWindow title="Find" showCloseButton="true" close="closeMe();"
            styleName="formPanel" horizontalScrollPolicy="off" verticalScrollPolicy="off"
            width="400" height="200">

    <mx:DataGrid dataProvider="{results}" width="100%" height="100%">
        <mx:columns>
        <mx:DataGridColumn dataField="type" headerText="Address"/>
        </mx:columns>
    </mx:DataGrid>

  <mx:Button label="Go" height="20" styleName="buttonGo" click="srv.send()"/>
</mx:TitleWindow>

Had a look at the xml. It could be that the first occurance of type is at a top level, but from then on type is an element of address_component.

Maybe try address_component.type as the datafield of the DataGridColumn? Or set the dataprovider to results.address_component?

Edit Update

Because its reading XML, maybe set resultFormat="e4x" inside the <HttpService ..> tag, and have an XMLListCollection awaiting the result:

<mx:XMLListCollection id="xc" source="{srv.lastResult.result}"/>

<mx:DataGrid id="dg" dataProvider="{xc}">

In debug mode, set a watch on XC to make sure its being populated
