How to Mapping a Collection of embedded Objects Question

Hello.

I have been reading the Java Persistence with Hibernate book and on page 258 it describes how to Map a collection of embedded objects. I've been able to implement this mapping successfully. However when I try to access the mapped collection of embedded objects, I get the following error:

Code:

org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: Transaction.states, no session or session was closed

Now I understand why this is happening; as my Transaction is detached and Transaction.states have not been initialized; but I thought since these states are embedded in the Transaction class they would be automatically populated when I get the Transaction from the database, via a session.get(type, id).

Any help with this is welcomed and appreciated.

Thanks!

I finally got this resolved by added the fetch = FetchType.EAGER property to the @CollectionOfElements. The funny thing is the book did not indicate this.

Huh, go figure.
