When working with datagroup, I noticed that its children are not immediately updated when the dataprovider is updated. Calling your scrolling code in a callLater function will have the updated number of children to scroll, if the validateNow doesn't work for your situation. Another option is if you have virtualLayouts set to false, you can catch the rendereradd event of the datagroup and run your scroll code there.
@Alex, thanks for the idea of validateNow. I was working on animating the adding and removal of items in a datagroup and that may be what I was missing.
