Hi Tracy, What you've described is exactly where I've been looking.
To be honest I'm not sure what the dataProvider looks like or what it is beyond being an 'object' - in the Flash MX IDE I could look at what was getting passed back and forth in the remoting debugger, but I'm not sure how to do that in Flex What I do know is that accessing remoteObject.call.result.items as the dataProvider appears to populate the label fields of the ComboBox (Looks like a populated comboBox as intended), but there does not appear to be a selectedItem.label nor a selectedItem.data available on selection (though selectedItem itself is an [object Object] - how do I get to see what that object and it's properties are? How can I post you a bit of the dataProvider?
