At this moment, STV does not handle failure event of operations on asynchronous stores.
Ex If we delete a row on an arrayofobjectssection (bound to a network datastore) and the delete request fails. STV assumes the row has been deleted successfully, when in fact is has not been deleted.
I think that this kind of events should be handled (insert, delete, move, update) ,and run appropriate cell, section, or model actions.
Furthermore, it would be great to know when a datastore's asynchronous operation starts or ends, so we could present an activity indicator.
