ComboBox [type Function] XML problem

Question

What I'm trying to accomplish is populating a ComboBox
component's labels and data using an Array that's created from an
XML data source. I know that I can populate the ComboBox in
ActionScript using this:
comboBox.labels = ["itemA",'itemB","itemC"];
-OR-
var cbArray:Array = ["itemA",'itemB","itemC"];
comboBox.labels = cbArray;
However, I'm running into problems when the Array is created
from my XML datasource, like this:
for (var g:Number = 0; g < aChildren.length; g++) {
var aItem:String = aChildren[g].firstChild.firstChild;
cbArray.push(aItem);
comboBox.labels = cbArray;
trace(cbArray);
I've left all of the XML details (load, onload, etc.) because
I don't think that the problem is there. In my example, when I test
the movie, the trace(); function displays the correct info, but the
comboBox component is populated only with an identical number of
instances:
[type Function],[type Function],[type Function],[type
Function],[type Function]...
I couldn't find a thread anywhere with my particular problem.
Any ideas?

Answer 1

I'm answering my own question. Hopefully someone will still
benefit from it being here. Someone I work with is a JavaScript
guru type and he worked through this with me. For some reason, the
aItem variable isn't being perceived as a string. So, the solution
I found was to alter the code here:
var aItem:String =
aChildren[g].firstChild.firstChild.toString();
This fixed my problem.
