So something like ......:
[Bindable]
private var photoFeed:XML;
private function photoResultHandler(event:ResultEvent):void
{
photoFeed = event.result as XML;
}
<mx:HTTPService
id="photoService"
url="http://api.flickr.com/services/feeds/photos_public.gne";
resultFormat="e4x"
result="photoResultHandler(event);"
fault="photoFaultHandler(event);"
/>
And you also state:
You wrap the XMLList in an XMLListCollection:
Var xlcResult:XMLListCollection = new XMLListCollection(xlResult)
I dont understand how this is better. I'm not disputing it. I just dont
understand.
What will this enable me to do that I'm not doing now? (Again, I'm
asking to understand, not to dispute)
If you just want to give me a reading list thats fine too.
thanks for your time.

Yes, binding to lastResult is, as you are seeing, hard to debug. Use a
result handler.

For the immediate problem, add some code to the function that checks
the first parameter for null, and returns a null value of the
appropriate type in that case.
But for a more robust application, you should stop using lastResult.
Direct use of lastResult is really only appropriate for prototyping.
You are much better off using a result handler to process the result,
handling the special cases, and putting the appropriate values into
variables that you then use for the binding.
