List Control - Disable Selection Color/Highlight

In putting together a List control this afternoon, I discovered an annoying little property about Lists... you can't "disable" the selection color that occurs on a list item when you "select" an item (click on it). For my purposes, my list needed to be selectable for dragging elements to re-order, but I didn't actually want to select a given item in the list. The order of items was all I wanted to impact the order of series rendering in a stacked column chart...

Anyway... the solution I came up with was to specify a selectionEasingFuction style which returned "0". 

  
  
  
      private function myEasingFunction(t,b,c,d):Number
      {
          return 0
      }

This is how I did it... A little hokey, but it works (the selectionEasingFunction didn't work for me on a TileList control)

Add these two tags to your list control called ListName: selectionDuration="5000" itemClick="{ListName.selectedIndex=-1}"

The selectionDuration makes it so that it takes Flex long enough to draw the background that you won't see a flicker like you would if you do not include that parameter.

How would you also disable the rollover for the tileList? I cannot find this anywhere.
