To be more exact, after PendingOrder updated:

public int updateDeliveryInfo(
RestaurantRepository rr,
Address deliveryAddress,
Date deliveryTime, boolean force) {
..............................................

this.deliveryAddress = deliveryAddress;
this.deliveryTime = deliveryTime;
................................................
}

at what moment the changes are in DB?
Dear Chris!
Could you explain one thing about transparent persistence I did not catch? When the PendingOrder updated how the changes are posted to DB? Whose duty to call the save() method on Hibernate? Is it Spring when it closes transaction after facade method returns success? Thank You!
