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
