Error when building File Info Panel

Question

I'm trying to rebuild my custom XMP File Info panel so that it will work in CS5, but am getting the following error:
Description     Resource     Path     Location     Type
1046: Type was not found or was not a compile-time constant: XMPComboBox.     DKimageXMP.as     /dkphoto/as     line 223     Flex Problem
The line causing the problem is:
private function updateComboBox(comboBox:XMPComboBox, xmpPath:String): void
     //blah blah blah
Near the top of my actionscript file I have
import com.adobe.xmp.*;
So I don't understand why XMPComboBox is not a valid type?

Hi Stefan
Thanks for your help, that fixed the problem.
I'm now having trouble with a TextInputMRU - when I give it a dataProvider the panel builds okay, but appears empty when viewing it in Photoshop.
My panel code looks like this:
<?xml version="1.0" encoding="utf-8"?>
<fi:XMPForm
          xmlns:mx="http://www.adobe.com/2006/mxml"
          xmlns:fi="com.adobe.xmp.components.*" width="100%" height="100%"
          label="dkphoto" >
     <mx:Script>
          [Bindable]
          private var CountryList:Array = new Array("Afghanistan",
               "Åland Islands",
               "Albania",
               "Zimbabwe");
     </mx:Script>
     <fi:XMPNamespaces>
          <fi:XMPNamespace prefix="Iptc4xmpExt" value="http://iptc.org/std/Iptc4xmpExt/2008-02-29/" />
     </fi:XMPNamespaces>
     <fi:XMPFormItem label="$$$/xmp/Iptc4xmpExt/CountryName=Country Name" labelTooltip="$$$/xmp/Iptc4xmpExt/CountryName_tooltip=The name of a country of a location. This element is at the second level of a top-down geographical hierarchy." >
          <fi:XMPTextInputMRU id="LocationCreatedCountryName1" xmpPath="Iptc4xmpExt:LocationCreated[1]/Iptc4xmpExt:CountryName" width="300" dataProvider="{CountryList}" />
     </fi:XMPFormItem>
</fi:XMPForm>
Any idea what the problem would be there?
Thanks
Dave
