Datagrid itemrenderer list rowcount not changing with data

Question

I have a datagrid with an itemrenderer.  the itemrenderer is a list component.  I populate the list with different values for each datagrid row.  this works fine.  However, I want the list to reset the rowcount for each datagrid row.  This is not happening.  if the first datagrid row list box is 3 rows every list box in that column is 3 rows no matter what i do.  here's my code:
<mx:List xmlns:mx="http://www.adobe.com/2006/mxml" rowCount="1">
<mx:Script>
  <![CDATA[
   import mx.utils.ObjectProxy;
   import mx.collections.ArrayCollection;
   import mx.utils.ArrayUtil;
   [Bindable] private var arr:Array;
   override public function set data( value:Object ) : void
    super.data = value;
    if(value != null && value.MEET is ArrayCollection)
     var len:Number = value.MEET.length;
     arr = new Array();
     for each (var obj:ObjectProxy in value.MEET){
      arr.push(obj.DAYS);
     this.dataProvider = arr;
     //labelField = "DAYS";
     this.rowCount = len;
    else if (value != null && value.MEET is ObjectProxy )
     this.rowCount = 1;
     this.dataProvider = value.MEET;
     this.labelField = "DAYS";
    else
     this.rowCount = 1;
  ]]>
</mx:Script>
</mx:List>

Hello !
This trick makes my application freeze...
I've just an advancedDatagrid populated with arrays, and a list as renderer on some of its columns... I've got exactly the same problem (rowCount that is always the same, for all of my renderers instances), but your solution doesn't work it out...
Any idea ?
thanks a lot
