Using an ArrayList as the dataProvider for a ComboBox (FB4)

[the_grifter]

I come from Flex Builder 3 and have run into what I'm sure is a real simple problem.  I don't know how to use an ArrayList as the dataProvider for a ComboBox.  Here's what I have in ActionScript:

[Bindable]

private var _cbxdp:ArrayList = new ArrayList ([

   {label: '1 year'},

   {label: '2 years'},

   {label: '3 years'} ]);

And here's the combobox:

<s:ComboBox id="cbxWarrantyLength" width="125" dataProvider="{_cbxdp}" />

Compiles fine, etc.  But when it loads the only thing in the combo box options are:  [object Object] (three times, one for each option).  In Flex Builder 3 all I would do is set the dataProvider to be like {_cbxdp.label} but I'm not sure how to do it in FB4.  Any hints?

The code worked for me, I've pasted the complete code below for reference that I put in an AIR application ( just for quick testing)

<?xml version="1.0" encoding="utf-8"?>

     <s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"

             xmlns:s="library://ns.adobe.com/flex/spark"

             xmlns:mx="library://ns.adobe.com/flex/mx">

     <fx:Script>

          <![CDATA[

               import mx.collections.ArrayList;

               [Bindable]

               private var _cbxdp:ArrayList = new ArrayList ([

                    {label: '1 year'},

                    {label: '2 years'},

                    {label: '3 years'} ]);

          ]]>

     </fx:Script>

     <s:ComboBox id="cbxWarrantyLength" width="125" dataProvider="{_cbxdp}" />

</s:WindowedApplication>
