Itemrenderer with images doesn't work correctly if variableRowHeight="true"?

Question

Hi all,
I have a problem to use itemrenderer in my project:
I have to show some images in one of my DataGridColumn:
<mx:DataGridColumn id="datasetcolumn" headerText="DataSet"
dataField="dataSetList"
width="240"itemRenderer="DataSetRenderer"/>
The dataSetList is an arraycollection of images;
I use Tile as the itemrederer, My DataSetRenderer is:
<?xml version="1.0" encoding="utf-8"?>
<mx:Tile xmlns:mx="
http://www.adobe.com/2006/mxml"
horizontalScrollPolicy="off" width="90%" height="100%" >
<mx:Metadata>
[Event(name="showCaddwgNOVWebDataset",
type="flash.events.Event")]
</mx:Metadata>
<mx:Script>
<![CDATA[
import mx.controls.Image;
import mx.controls.AdvancedDataGrid;
import mx.core.IFlexDisplayObject;
import CETEvent.*;
import view.util.*;
import mx.collections.ArrayCollection;
[Bindable] public var myarr:ArrayCollection = new
ArrayCollection();
override public function set data(value:Object):void{
super.data = value;
myarr = value.datasetList;
this.myrep.dataProvider = myarr as ArrayCollection;
]]>
</mx:Script>
<mx:Repeater id="myrep" visible="true" >
<mx:Label text="{myrep.currentItem.itIconName}"/>
<mx:Image id="datasetImg"
source="{myrep.currentItem.itIconName}"
useHandCursor="true" buttonMode="true" mouseChildren="false"
toolTip="{myrep.currentItem.itName}"/>
</mx:Repeater>
</mx:Tile>
The problem is:
Whenever you change the column size or scroll down the
datagrid,
the images will be added again.
if the datasetlist is changed the old images doesn't clean up
and
all the images messed up
Any suggestion is appretiated!
Thanks in advance

I loved Ben's suggestion because it promised to be a low-effort workaround, but, alas, I get the same problem: "lvlib is already loaded from this path...".
I tried Olivia's workaround for CAR 124214. It worked great for the simple lvproj that is posted above. (Hooray!) It didn't work so well in my real project, that has about 30 lvlibs and lvclasses. About 3/4 of the way through the save, I got a compiler error and LabView crashed. (Boo!) I submitted the crash log on this, but it's hard to imagine how anyone in R&D could make any progress debugging this without the source code. (And I can't submit the source because I can't export a copy of it!)
Anyway, thank you very much Ben and Olivia for your suggestions. I have lvclasses embedded in lvlibs (primarily for organizational reasons) and since LabView tanked while saving one of those, perhaps the workaround doesn't work in this case. I may try again after removing the lvclasses from the lvlibs so that the hierarchy is flatter.
