The scope of the Hibernate session must match the scope of any lazily loaded objects or collections. That's one of the rules of Hibernate (or any other ORM that I've used, for that matter). Putting a proxy object in web session scope while the Hibernate session is in request scope breaks that rule. You need to either use a transfer object, or cause Hibernate to initialize the proxy by either setting the lazy attribute to false, or using Hibernate.initialize(). You can also re-associate the object with the Hibernate session as was mentioned before. [EMAIL PROTECTED]
