Dear all,
     I write an entity like this:
@Entity 
public class Employee 
{
     @Id
     private long id;     
     private String name;
     
     @OneToMany
     private Mao<String,EmpDetail> detail=new TreeMap<String,EmpDetail>();
 
     //set ,get functions pass
 
     @Entity
     public static class EmpDetail
     {
              @Id
               protected long id;
               protected String address;
               //set ,get functions pass
     }
}
 
I  delete an EmpDetail like this:

    em.remove(em.getReference(EmpDetail.class,4)); // em is the entity manager


  I delete the record successful but the last one. 
Exception is here:   javax.persistence.EntityNotFoundException:deleted entity passed to persiste:(...Employee$EmpDetail#<null>)

some one knows what is going on?  thank you!
