RE: Hibernate - OSIV
With OSIV every user will have a different hibernate-session, hence a different hibernate object, so your example would work. But your approach is wrong. For your example I would make a SurveyResult object that holds a reference to your hibernate Survey object. Problem solved. No need to play jiggle with transient properties and object identities in hibernate.

I have looked at OSIV in Spring and OSIV in Wicket. I can't seem to find
any examples that will help me to determine the problem. I have included
all the code and xml configuration that I believe is relevant. Any help
would be appreciated. Also a clean example of how to setup Spring +
Hibernate OSIV in the wiki would be a big help.
Here is what I have [a very simplified example]:
@SpringBean
private IProductDao dao;
// the following two lines are in the constructor for the page
Product product = dao.findBySku(sku);
ListOption options = product.getOptions();// this is lazy loaded -
Yes, I know in this example I could just eager fetch it but other times I
don't need the options
// a generic dao
public abstract class GenericDaoT extends DomainObject extends
HibernateDaoSupport
// the product dao
public class ProductDao extends GenericDaoProduct implements IProductDao {
