Justin Mclean resolved FLEX-11238.
----------------------------------
Resolution: Fixed
Fixed in 4.9 or 4.10, code no longer produces RTE. However order of item may
not be what is expected as refresh was not called after setting sort to null.
> exception in ListCollectionView.addItemsToView

> Workaround: have a fake filter that always returns true?

> available in the Build dropdown.
