Hello,

I have declared a <natural-id .../> that includes a <many-to-one .../> relation. I'm trying to use it in my Dao but I'm getting an org.springframework.dao.InvalidDataAccessApiUsageException: org.blah.Owner; nested exception is org.hibernate.TransientObjectException: org.blah.Owner

My test is:
Case case = new Case(new Owner("me"), ...);
assertNull(dao.findByNaturalKey(case));

The findByNaturalKey is:
NaturalIdentifier naturalId = Restrictions.naturalId();
naturalId.set("owner", case.getOwner());

It works for the other natural keys, how do I include the owner?

Thanks

I changed the dao:
naturalId.set("owner", case.getOwner().getCompanyId());

That fixed it when the owner isn't save yet.
Once it is, I'm getting a new exception:
org.springframework.orm.hibernate3.HibernateSystemException: could not get a field value by reflection getter of org.blah.Owner.companyId; nested exception .......
Caused by: java.lang.IllegalArgumentException: Can not set java.lang.Integer field org.blah.Company.companyId to java.lang.Integer

Now I'm really stuck...

solved it by adding an alias and including the alias in the naturalId.set("owner"...
