Code between sessionFactory.openSession() and session.close():

Code:

session.find("from AttributeType");

Full stack trace of any exception that occurs:

Name and version of the database you are using: SQL Server 2000

The problem I am having is that despite the finder retrieving the list of AttributeTypes, and correct SQL is generated as I can see it in the SQL profiler, the returned AttributeTypes are the enhanced CGLIB proxies and not the initialized AttributeTypes.

Code:

AttributeType$$EnhancerByCGLIB$$

This is a pretty basic operation that I've done in the past many many times. However, on this occassion something (I'm sure that it is fundamental) is disallowing the entity from being correctly initialized.

If I iterate over the list and individually Hibernate.initialize or access a property the AttributeTypes are initialized. However, this shouldn't be the case, they should have been initialized immediatley upon return of the finder.

Please advise.

Are you certain you haven't upgraded to Hibernate 3 ?

Lazy Initialization is the default in H3.

Definitley using 2.1.8 although plans to migrate are being reviewed for next release.

Despite using lazy proxies, if I'm issuing a session.find(from EntityName) shouldn't this return the initialized list of entities?

We're not talking lazy associations or collections. This is the primary entity being queried.
