[flexcoders] DataGrid itemEditEnd event fails with non-text itemEditors

[luciddream54321]

Hi,

I have an editable DataGrid and have specified a function to handle
the itemEditEnd event.  One of the columns is using a NumericStepper
as an itemEditor.  When I edit that column I get a run-time error when
the itemEditEnd event fires because it appears Flex is trying to
access the column's "text" property which doesn't exist with a
NumericStepper.  

This problem isn't limited to NumericStepper but also
occurs when I use a DateField and surely other itemEditors as well.
 What do I need to do to prevent this from happening?

This is the error I get when I click out of the column after editing it:

ReferenceError: Error #1069: Property text not found on
mx.controls.NumericStepper and there is no default value.

Here is an example application to illustrate the problem:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
layout="absolute">
        <mx:Script>
                <![CDATA[
                        import mx.collections.ArrayCollection;
                        
                        [Bindable]
                        public var numbers:ArrayCollection = new
ArrayCollection([{number:1}, {number:2}]);
                        
                        public function onItemEditEnd(event:Event):void
                        {
                                // Flex will crash before it gets here
                        }
                ]]>
        </mx:Script>
        
        <mx:DataGrid dataProvider="{numbers}"
itemEditEnd="onItemEditEnd(event)" editable="true">
                <mx:columns>
                        <mx:DataGridColumn dataField="number"
itemEditor="mx.controls.NumericStepper" />
                </mx:columns>
