Hello,
i'm digging in to JPA-RS but i don't fully understand the way relations are managed.
Let's say i create an Employee entity, as provided below.

@Entity
public class Employee {

  @Id
  @GeneratedValue
  private Long id;

  @ManyToOne
  @JoinColumn(name = "MANAGER_ID")
  private Employee manager;
}


First i would create an entity without an manager (boss: id 1), and then create another one (staff member), whose manager would be the boss:
POST http:// ... /entity/Employee
{
  "manager": {
    "_link": {
      "href": "http:// ... /entity/Employee/1"
      "method": "GET",
      "rel": "self"
    }
  }  
}

But this creates an additional Employee entity, which is set up as the manager for the intended employee.

Am i missing something very important here?
Thanks in advance

I'm somehow desperate for an answer on this? It's driving me nuts.
