This method is useful after an optimistic concurrency error to bring items into a state for another attempt. It updates the state of the primitive fields and properties on the objects.

Note

If an object is on the many side of a one-to-many relationship, the foreign key on the object will be set and the object pointer for the other side of the relationship will be set to the new value.
