[flexcoders] Re: Strange List behaviour
Thanks for all your help. Doug, your idea gave me a different idea of
something to try which seems to work
mx:Model id=listData
{listService.lastResult.things}
/mx:Model
mx:List
id=list
dataProvider={listData.thing}
labelField=name /
I still don't understand why that works and what I previously had
doesn't, because you are referencing exactly the same object (i.e. an
array) but in a different way. I guess it's all to do with the crazy
Model...

The code:
...
mx:HTTPService
id=listService
url=...
/
mx:Model id=listData
{listService.lastResult.things.thing}
/mx:Model
mx:List
id=list
dataProvider={listData}
labelField=name
/
...
and the XML that results from the HTTPService send:
things
thing
nameMyName/name
valueMyValue/value
thing
...
things
[flexcoders] Re: Strange List behaviour
I need the model because I use the data elsewhere as well. I thought
the labelField property of List told it which property to use for
labels (hence my setting it to name). I also don't think I need
another layer of properties in the List result because I should be
able to use Objects (so I can get the value property of the Object
from the List without having to do lots of silly stuff).

Firstly, you don't need the Model tag:
mx:List
id=list
dataProvider={listService.lastResult.things.things}
labelField=name
/
Maybe you need to tell List what properties it should be using for
labels. It
also looks like you maybe need one extra level of properties in the
service
results.

RE: [flexcoders] Re: Strange List behaviour
I have never been comfortable with predicting how Model would convert my
xml, so I never use it. Instead, use an instance variable, either typed
XML, or XMLListCollection, set resultFormat=e4x.
Also, I never bind directly to last result because, as you have seen, it
is difficult to debug. Instead, use a result handler function:
Private function onResult(oEvent:ResultEvent):void {
_xmlResult:XML = XML(oEvent.result);
trace( xmlResult.toXMLString()); //this will show you exactly what the
xml is
_xlcThings = new XMLListCollection(xmlResult.things.thing); //bind your
list to this collection
Actually, I may see the problem in your code:
{listService.lastResult.things.things}
Should be:
{listService.lastResult.things.thing}
But still, go with xml.
