Flex - overriding scrollToIndex in HorizontalList to animate scrolling

I'm not posting how to do it for list, as that's not what i was working on - but it should be fairly straight forward and should use very similar (if not the same code).

 
override public function scrollToIndex(index:int):Boolean{
//super.scrollToIndex(index);
var newVPos:int;
var newHPos:int;
 
var firstIndex:int = scrollPositionToIndex(horizontalScrollPosition, verticalScrollPosition);
var numItemsVisible:int = ((listItems.length - offscreenExtraRowsTop - offscreenExtraRowsBottom) *
(listItems[0].length - offscreenExtraColumnsLeft - offscreenExtraColumnsRight));
if (index >= firstIndex + numItemsVisible || index < firstIndex)
{
newVPos = Math.min(indexToRow(index), maxVerticalScrollPosition);
newHPos = Math.min(indexToColumn(index), maxHorizontalScrollPosition);
 
try
{
iterator.seek(CursorBookmark.FIRST, scrollPositionToIndex(horizontalScrollPosition, verticalScrollPosition));
//super.horizontalScrollPosition = newHPos;
//super.verticalScrollPosition = newVPos;
 
var p:Parallel = new Parallel(this);
var ap:AnimateProperty = new AnimateProperty(this);
var ap2:AnimateProperty = new AnimateProperty(this);
ap.property = 'verticalScrollPosition';
ap2.property = 'horizontalScrollPosition';
 
ap.toValue = newVPos;
ap2.toValue = newHPos;
 
p.addChild(ap);
p.addChild(ap2);
 
p.play();
 
}
catch(e:ItemPendingError)
{
}
return true;
}
return false;
}
