(to do)
Describe that adding a new m2m association for two new entities (where the key properties hold the RoundtripOriginalAttribute atribute) requires special action because after submit changes the entities will have their keys updated but are not processed in the correct order: A AB B. When updating AB, AB.A is correcly setup, but AB.B is not (it will have its initial key B.Id == 0, while AB.BIs is already updated with the server provided key, i.e., AB.BId != null). As a consequence, B.ASet will no longer contain the entity B.
