[flexcoders] HTTPService BUG can't read RSS xml with single item

Wed, 06 Feb 2008 08:36:42 -0800 

  Hi as I was using HTTPService I found that if the
  xml file has only one item in it HTTPService returns
  arreycollection with no elements in it. On the other
  hand if you add one more item in the input xml file,
  then it returns an arraycollection with 2 elements.

  I guess this is a bug!!!! Here is the CODE:

        /****************************
         ****************************/

               Main Application

        /****************************
         ****************************/

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
layout="absolute" initialize="portFolio.send();">
<mx:HTTPService id="portFolio" url="oneNode.xml" result="newArray =
portFolio.lastResult.RDF.item"/>
<mx:Script>
        <![CDATA[
                import mx.collections.ArrayCollection;

                [Bindable]
                public var newArray:ArrayCollection = new ArrayCollection();
        ]]>
</mx:Script>

        <mx:DataGrid id="newDG" x="10" y="10" dataProvider="{newArray}"/>

</mx:Application>
