addChangedPropertyName is used to inform the changeObject that additional fields were updated besides the ones sent by the client. If during the update process, you decide to update a new field based on some condition, you change it, you commit it and then notify the change object that property has been changed, so, once clients get the notification, they will know that some additional change in a field has been made. --
