Hello,



I have this message in the problems box. I could not figure
out the problem. I was following Sho Kuwamoto's photo search
example.



1119: Access of possibly undefined property result through a
reference with static type mx.rpc.http.mxml:HTTPService.



Here is the code.



<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute">



<mx:HTTPService id="service" url="
http://www.flickr.com/services/rest/?method=flickr.photos.search&amp;api_key=a7c643c2f86d8baf1b51186...

<mx:states>

<mx:State name="results">

<mx:SetProperty target="{panel1}" name="width"
value="100%"/>

<mx:SetProperty target="{panel1}" name="x"/>

<mx:SetStyle target="{panel1}" name="horizontalCenter"
value="0"/>

<mx:SetProperty target="{panel1}" name="y"/>

<mx:SetStyle target="{panel1}" name="verticalCenter"
value="0"/>

<mx:SetProperty target="{panel1}" name="height"
value="100%"/>

<mx:AddChild relativeTo="{canvas1}"
position="lastChild">

<mx:TileList
dataProvider="{service.result.rsp.photos.photo}" width="619"
height="314" horizontalCenter="0"
verticalCenter="14"></mx:TileList>

</mx:AddChild>

</mx:State>

</mx:states>

<mx:Panel x="147" y="10" width="338" height="82"
layout="absolute" title="Photos" id="panel1"
resizeEffect="Resize">

<mx:Canvas height="100%" width="100%" id="canvas1">

<mx:Label x="25" y="10" text="Tags"/>

<mx:TextInput x="65" y="8" id="input"/>

<mx:Button x="253.5" y="8" label="Find"
click="currentState='results'; service.send()"/>

</mx:Canvas>

</mx:Panel>



</mx:Application>



Thank you.

I found a way to fix this. In dataProvider, use "lastResult"
instead "result" so, like this:

<mx:TileList
dataProvider="{service.lastResult.rsp.photos.photo}"
itemRenderer="thumnail"></mx:TileList>



Also, listItemRenderer is not existing anymore, use
"itemRenderer"
