> I have a many-to-many relation between two objects :
> {code:title=Project.java|borderStyle=solid}
> @Entity
> public class Project {
>   private List<Viperson> managers;
>   @ManyToMany(targetEntity = Viperson.class)
>   @JoinTable(name = "PRJMANAGER", joinColumns = @JoinColumn(name = "PROJECTID", nullable = false), inverseJoinColumns = @JoinColumn(name = "VIPID", nullable = false)) 
>   public List<Viperson> getManagers() {
>     return managers;
>   }
> }
> {code}
> {code:title=Viperson.java|borderStyle=solid}
> @Entity
> public class Viperson {
>   private List<Project> projects;
>   @ManyToMany(mappedBy = "managers", targetEntity = Project.class)
>   public List<Project> getProjects() {
>     return projects;
>   }
> }
> {code}
> And the following test (actually, it is a code from spring batch HibernateCursorItemReader I put in a testcase) : 
> {code}
> @Test
> public void testSelectAll() {
>   StatelessSession statelessSession = sessionFactory.openStatelessSession();
>   ScrollableResults cursor = statelessSession.createQuery("from Project").scroll();
>   Object[] data = null;
>   if (cursor.next()) {
>     data = cursor.get();
>   }
> }
> {code}
> data contains a {{Project}} but {{managers}} field is *null*, +even if I add eager fetching+. I have also a {{OneToMany}} in the {{Project}} class. This one is well loaded (i have a {{PersistentBag}}).
> Is there anything I miss ? I suspect a bug on that.
