Hibernate version:3.1b5 + 3.1b3 annotations
I'm encountering a problem with using a base entity (assigned using @EmbeddableSuperclass) in a @ManyToOne relationship. Long story short: When attempting to save, it is failing due to a null entry being saved to the fk column. It seems it is failing to pick up the id of the FK class (which uses the base entity)....when I remove the base entity from the hierarchy and place the id methods in the fk class itself, it finds the id and saves the otm/mto just fine.
Again, this works when not using an @EmbbedableSuperclass
Usage
Code:
...
Company c = new Company();
c.setId(1);//there is a company record with this id in the database
Address a = new Address();
a.setCity("Norman");
a.setState("OK");
a.setStreet1("123 Main St.");
a.setZip("73072");
a.setCompany(c);
dao.save(a);
...
