I would not expect this to work. The value of verticalScrollPosition must be <= maxVerticalScrollPosition

I've attached a screenshot so you can see what I'm experiencing, and here is the code: private function moveToNode(event:TreeEvent): void { var nIndex:int = (event.target as Tree).itemRendererToIndex(event.itemRenderer); (event.target as Tree).selectedIndex = nIndex; (event.target as Tree).verticalScrollPosition = nIndex; } It get's called on the Tree's itemOpen and itemClose events: itemOpen="moveToNode(event)" itemClose="moveToNode(event)" If I comment out the "verticalScrollPosition" line the problem goes away. My goal is this: When someone opens a tree node, I want to set focus to it, and bring it and it's children into view so the user does not have to scroll if they open a node near the bottom of the control. Maybe there is a better way to do this? If I don't get a quick answer I'll put together a test case application and submit to the group.
