I'm just wondering why Adobe wouldn't already have these kinds of 
checks in place.  I haven't looked at Label code specifically, but I 
see these kinds of checks in place all the time in the Framework code.  

If you just use a label without extending it (I didn't see anything in 
the logic to suggest why extending it was necessary), do you still get 
the error?  If so, this should probably be filed as a bug.  If not, it 
would be interesting to try to find out what the difference is.

by the way, I'm using RemoteObject to access my CFC, is it possible
that the itemRenderer is firing before the data is back?
How would I make the data populate the ArrayCollection fooAC first
before rendering the datagrid? If this is the case anyways...

You might try adding this Greg:

override public function set data( value : Object ) : void
{
 if (value != null)   super.data = value;
}

The data property will be null until the service call has returned and
populated the collection.

Label already implements IDropInListItemRenderer and IDataRenderer.  
Presumably correctly...

Correct.  Perhaps the collection isn't bound to the dataProvider
correctly.

What do you mean?
The collection shows in the dataGrid just fine, it's the custom
itemRenderer that isn't working?
Is there something else I can provide to check this?

I changed the PriceLabel.as file to this..

package com.renderers {
import mx.controls.Label;
import mx.controls.listClasses.*;
import mx.controls.Alert;

public class PriceLabel extends Label {

override public function set data( value : Object ) : void

override protected function
updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void {
//super.updateDisplayList(unscaledWidth, unscaledHeight);
//Alert.show(data.toString());


}
}
}


I added a breakpoint after the commented out alert and still this.data
shows null...
Any other ideas? I'm out of them

data is probably null the first time that updateDisplayList is called. 
You can either put your conditional logic in the commitProperties() or
set data() methods.

Override public function set data( value : Object ) : void
{
 if (value != null)
 {
  super.data = value;
  this.text = data.myField;  // might want to debug this line to
see the data
 {
}
