TileList Drag/Drop functionality is broken if the same item is dropped twice or more

Question

Hi Folks.
This is quite frustrating.
I'm using two tilelists and you can drag items from one to
the other.
If you drag an item more than once then when you rollover
that item it highlights the second(or most recent) version of the
item you dragged.
Basically the second tile list is containing exact copies of
the first, so that when you rollover an item it is behaving as if
only the most recent addition to the component is there.
Here is the code.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute" width="560" height="341">
<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
[Bindable]
private var listArray:Array=[
{label: "item0", data: 0},{label: "item1", data: 1},
{label: "item2", data: 2},{label: "item3", data: 3},
{label: "item4", data: 4},{label: "item5", data: 5},
{label: "item6", data: 6},{label: "item7", data: 7}];
[Bindable]
public var cartFilterCol:ArrayCollection ;
]]>
</mx:Script>
<mx:Canvas width="568" height="340">
<mx:TileList
id="filterTilelist"
direction="vertical"
dataProvider="{listArray}"
itemRenderer="mx.controls.Button"
allowMultipleSelection="false"
dragEnabled="true"
width="219"
borderStyle="inset" height="228" x="48" y="36">
</mx:TileList>
<mx:TileList backgroundColor="#ffffff"
dataProvider="{cartFilterCol}"
dropEnabled="true"
allowMultipleSelection="false"
dragMoveEnabled="true"
dragEnabled="true"
borderStyle="inset"
columnCount="1"
height="228" width="194" x="275" y="36">
</mx:TileList>
</mx:Canvas>
</mx:Application>
I think this is the issue here
https://bugs.adobe.com/jira/browse/SDK-11894
It seems to suggest that this issue is resolved but it
doesn't go into details. Can anybody help me, even an ugly hack
would do? Have tried several things like manually setting the
mx_internal_uid on object beign dragged before it is dropped but no
luck so far. I'm using Flex builder 2.0.1.
Thanks

Check that you still have the "Bookmarks Toolbar items" placed on the Bookmarks Toolbar
* Make sure that you have the "Bookmarks Toolbar" visible: "View > Toolbars"
* Check in "View > Toolbars > Customize" that the "Bookmarks Toolbar items" is on the Bookmarks Toolbar
* If the "Bookmarks Toolbar items" is not on the Bookmarks Toolbar then drag it back from the Customize window onto the Bookmarks Toolbar
* If you do not see the "Bookmarks Toolbar items" then click the "Restore Default Set" button
You can only move the content from a toolbar onto other toolbars if all toolbars support that feature. You need to check that in the options of each toolbar.
