Have you determined that model.treeData contains valid xml?
(trace(treeData.toXMLString())) If it does, then the tree should work
like you have it. You will need to set the "labelField" property for
the label, or use a labelFunction if the data you want for the label is
not a top-level porperty/attribute of the item node.
Also, I am not familiar with RemoteObject, so this may not apply, but
you may need to set resultFormat="e4x". Also, if the data service was
HTTPService, I would do the result handler like this:
public function result( event:ResultEvent ):void {
var xmlResult:XML = XML(event.result);
trace(xmlResult.toXMLString());
model.treeData = xmlResult;
}
if you see good xml but are still having difficulty, take the model
class out of the picture and assign the dataProvider directly:
acTree.dataProvider = xmlResult;

Subject: [flexcoders] Re: Populate Tree with data from a query?
Hi,
That helps a bit, in my tree I am seeing the actual xml when I run my
application in flex. I have CFC function returning a string, I tried
having return xml and same thing.
*******************
After I make my remote object call in my result handler I have this:
public function result( data:Object ):void {
var event:ResultEvent = data as ResultEvent
model.treeData = event.result as XML;
}
It seems I have to cast it as XML otherwise in my "model" I get a 'type'
error
**************
In my model which is a [Bindable] class I have:
public var treeData:XML;
******************
And in the view I have
<mx:Tree id="acTree"
width="50%"
height="100%"
showRoot="false"
dataProvider="{model.treeData}"
change="treeChanged(event)"
/>
Any help appreciated as I am getting the actual xml in the tree. How do
you get the label to work also?
