Unfortunately that didn't work.
I don't even necessarily have to scroll down, once i touch the scroller it seems to redraw the items in the s:list.
forgot to mention the s:List has a itemRenderer.
If you're redrawing to reflect changes in the data itself, then you probably need invalidateList.
There's invalidateList and invalidateDisplayList.
invalidateDisplayList is to redraw the interface without refreshing the data.
invalidateList is when refreshing the data itself is what you're after.
Not sure if that will solve your problem, but give it a try
