JDO & Aggregation

Hi all

Im new to JDO so please bare with me ;)

Basically I have made a simple booking system with a Customer object, Room Object and a Booking Object

The Booking object has an attribute of Customer and room, the problem is that when i try and store the booking object it throws the following erros

com.solarmetric.kodo.runtime.UserException: The instance of type "kmthreecliffbay.Room" and with id "kmthreecliffbay.Room-958" is not managed by this PersistenceManager. The failed object is included in this Exception.

Any help or guidence would be greatly appreciated

Many thinks in advance

I think that the problem here is that you need to have the PersistenceManager (basically a data access object) create all instances of the object class it manages. So, that being said. Have you created an instance of the kmthreecliffbay.Room without using the persistence manager assigned to that type?
