Hi all, I have a unique issue I could use a hand with. Our model uses the following inheritance
Person -> User -> Customer. When purchases a unit and becomes a customer, they need to transparently be upgrade to a Customer. In doing so, I have to copy the UUID from the user to a customer. We can't change the UUID b/c it is referenced in other systems. Our storage system is functionally equivalent to single table inheritance. If I simply create a new instance and assign the same id, I receive this error. An object of type "com.spidertracks.aviator.model.user.Customer" with oid "com.spidertracks.aviator.model.user.Customer-d81d5fe0-6195-11e0-861a-005056c00008" already exists in this context; another cannot be persisted. The only way I've found around this is to perform the following steps. 1. load the original user, copy all the fields over that are not relationships (I.E *toMany *toOne). 2. Load all ids for entities that are related collections. 3. call entityManager.clear 4. Load all related collections 1 id at a time and link them to the new customer instance. 5. Call persist with the new customer. This is a bit of a pain, and as our entities get more complex this will be come messier. Is there an easier way to effectively deep copy the statemanager from one instance to another before persisting to avoid all these additional steps? Thanks, Todd
