Hi - I'm trying to sort out databinding the List component to a specific
property of objects in an ArrayCollection using Actionscript. I read
through a bunch of docs/tutorials online but either haven't found the right
one or am not understanding. Most of the examples show dataBinding using
MXML curly braces syntax.
The gist: I have a List component that I would like to bind to an
ArrayCollection, and have the List display a "name" property of each object
instance in the array. The ArrayCollection is populated with a bunch of
instances of a custom Class (code at bottom). I seem to be successful
binding it to the object instances - the List will display: [object
RP_Layer] - which is the Class name etc.
I define the ArrayCollection like this:
[Bindable]
public var layers:ArrayCollection = new ArrayCollection();
And assign the binding in my application mxml:
drawingCP.layerList.dataProvider = canvasB.layers;
--drawingCP is an instance of an AS class
--layerList is a List component
--canvasB is an instance of an AS class
--layers is the ArrayCollection
When I try to bind to the "name" property of the object instance like
below, I get an error.
drawingCP.layerList.dataProvider = canvasB.layers.name
Anyway, this may not be so clear.... ;-) I'll keep digging around but I
thought I would ask.

//------------- RP_Layer Class
package vo
{
[Bindable]
public class RP_Layer extends Object
{
public var name:String;
public function RP_Layer(name:String)
{
this.name = name;
}
}
}
