Comment (by stippi):
This looks still wrong to me. If you invoke
BOutlineListView::RemoveRow(someRow), the operation should be reversible
by invoking BOutlineListView::AddRow(someRow, itsPeviousIndex). With your
change however, all child rows of the row have been removed -- and leaked,
too. When you add the row back, it will have none of it's children
anymore. When the OutlineView::RemoveRow() code tries to figure out the
height of the entire subtree being removed, it uses an
RecursiveOutlineIterator. Why is that not working? I would search the
problem in that direction.
