Item Renderer in ActionScript

Question

I typed the devguide example on pp 719-720 into 2 separate
files: MyRenderer.as, test.mxml (both shown at end of post). IDE
gives the errors listed below. Any ideas? I thought the compiler
was smart enough to resolve the MyRenderer.CellField reference
using the xmlns="*" attribute of the mx:Application tag.
1120: Access of undefined property CellField. test.mxml
1172: Definition MyRenderer:CellField could not be found.
1120: Access of undefined property CellField. test.mxml
1120: Access of undefined property CellField. test.mxml
1120: Access of undefined property CellField. test.mxml
MyRenderer.as:
// ActionScript file
package MyRenderer {
import mx.controls.*;
import mx.core.*;
public class CellField extends TextInput
public function CellField() {
height=60;
width=80;
setStyle("borderStyle", "none");
editable=false;
override public function set data(value:Object):void {
super.data = value;
if (value != null) {
text = super.listData.text;
if (Number(super.listData.text) > 100) {
setStyle("backgroundColor", 0xff0000);
super.invalidateDisplayList();
test.mxml:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
height="600" width="600" xmlns="*">
<mx:Script>
<![CDATA[

Hi,
I'm sorry to bug you with a non-technical discussion, but I
am a recruiter in San Diego. My client is in need of 3 Senior Flex
Developers for their project. I have had an extremely rough time
finding someone for this position. Would you be interested in this
position, or do you know of anyone that might be? We do pay
referral fees. This position may be open to telecommuting.
Job Description:
They are in the midst of a major re-architecting of their
Corporate Management system utilizing many cutting edge
technologies. As it relates to the position they are using Flex as
their UI.
This is either a contract, or a full-time position.
Pay: Market Rate
Thanks for your help!
