I have a simple entity that connects to 4 other tables as a OneToMany relationship. When I fetch these collections, the correct number of results is returned. However, every object in the list is the same (the first object in the list). Furthermore, the objects are the exact same object reference.

Hibernate version:
Not sure what exact version. I believe its 3.1 (whatever comes with JBOSS 5.1

Mapping documents:
@OneToMany(fetch=FetchType.LAZY)
@JoinColumn(name = "person_nbr")
private List<Employment> positions;

@OneToMany(fetch=FetchType.LAZY)
@JoinColumn(name = "person_nbr")
private List<Email> emails;

@OneToMany(fetch=FetchType.LAZY)
@JoinColumn(name = "person_nbr")
private List<Role> roles;

@OneToMany(fetch=FetchType.LAZY)
@JoinColumn(name = "person_nbr")
private List<OtherId> otherids;


Name and version of the database you are using:
SQL SERVER 2005


I can post more debug stuff if you guys need, but not sure if any of it would help. (The sql looks fine and its pulling the data correctly just not all of it)

Make sure you have implemented hashCode and equals in Employment, Email, Role and OtherId; and the equals method checks key values.

LinHib.

Did implementing hashcode and equals fix this problem? I'm running into the same problem.

Have you check the id (Database id) of every object?
