was limited by the visible list count, it did not care if the insertion failed, it didn't maintain the BListItem::fHasSubitems field, neither fVisible, and it didn't invalidate the latch of the parent, if needed. * The "add item at end" also did not care if the item should be added to the visible list, too, it always did. * AddUnder() would have crashed with a NULL superitem. * _RemoveItem() now updates the fHasSubitems field as well. * _SuperitemForIndex() can now return the index of the superitem as well. * SortItemsUnder() did not check if the "underItem" if the items should be added to the visible list or not, it also just did. * SortItemsUnder() now invalidates the part of the visible list that may have been changed. * This fixed bug #662, and possibly #663, too (at least I could never reproduce it). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17812 a95241bf-73f2-0310-859d-f6bbb57e9c96
