I observed a strange situation using JPA in case of detached object.
If I want to use the Tenant (see bellow) object in JSF page accept the
tenantId field all fields are NULL. But before the return statement if
I access any of the member variable of Tenant Object it works file. I
tried with FetchType.Eager, but no luck.

Is it a known feature or BUG?

This is my entity class a Tenant has one or more user.

@Entity
public class Tenant{

   @OneToMany(mappedBy="tenant", cascade=CascadeType.ALL)
        Collection<User> hmsUserList = new ArrayList<User>();

.....
}

@Entity
public class User{

   @ManyToOne
        @JoinColumn(name="tenant_id")
        private Tenant tenant;

....
}

My function returns the Tenant Object as;

public Tenant myFunction(){

User user = em.find(User.class, ID);

//if add the bellow line it works
// user.getTenant().getName();

return user.getTenant();

}
