Hi, here is something that works, if you know cold fusion then
create a cfc that has the data you want and call it from a
webservice, other wise populate an xml file and call that.
Step one;
Create xml file - name it mydata.xml
<?xml version="1.0" encoding="UTF-8"?>
<obj>
<item>
<label>AL</label>
<data>Montgomery</data>
</item>
<item>
<label>AK</label>
<data>Juneau</data>
</item>
<item>
<label>AR</label>
<data>Little Rock</data>
</item>
</obj>
Step two;
copy and paste this code into flex builder
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
layout="absolute">
<mx:XML id="xmlData" source="myData.xml" format="e4x" />
<mx:Panel layout="absolute" title="States" left="5" top="5"
bottom="5" right="5">
<mx:ComboBox dataProvider="{xmlData.item.label}"
left="5" top="20"/>
<mx:ComboBox dataProvider="{xmlData.item.data}"
left="150" top="20" />
</mx:Panel>
</mx:Application>
The file myData.xml is used to populate the combo boxes

There seem to be numerous errors and typos in the Adobe Flex Help
files/PDFs and I'm hitting a snag here ...

help appreciated. Thanks.
