Hi,
preventDefault() works fine, thanks a lot Alex!
On to the <mx_internal_uid> mystery node then...
The problem only occurs when I set the selectedItem of the ComboBox but
can't see why that should present this problem?
[artistdata.xml]
<artistdata>
<categories>
<category id="0">
<label>Photographers</label>
</category>
<category id="1">
<label>Stylists</label>
</category>
</categories>
</artistdata>
[mxnode.mxml]
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
layout="absolute" initialize="onInitialize()">
<mx:HTTPService url="artistdata.xml" id="myService"
result="onResult(event)" resultFormat="e4x">
</mx:HTTPService>
<mx:Script>
<![CDATA[
import mx.events.ListEvent;
import mx.rpc.events.ResultEvent;
import mx.collections.XMLListCollection;
[Bindable]
public var myCollection:XMLListCollection;
private function onInitialize():void
{
myService.send();
}
private function onChange(p_evt:ListEvent):void
{
trace(myCollection.child('categories').children());
}
private function onResult(p_evt:ResultEvent):void
{
var XMLListData:XMLList = new XMLList(p_evt.result as
XML);
myCollection = new XMLListCollection(XMLListData);
categoryComboBox.selectedItem =
myCollection.child('categories').children().(@id == "0");
}
]]>
</mx:Script>
<mx:ComboBox id="categoryComboBox"
dataProvider="{myCollection.child('categories').children()}"
change="onChange(event)"></mx:ComboBox>
</mx:Application>
