[hibernate-dev] Hibernate invkoing onFlushDirty for umodified objects in Set

Hi All, I have a object with below relationship public class A { @Id @SequenceGenerator(name = "ID_GENERATOR", sequenceName = "Id_SEQ", allocationSize = 1) @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "ID_GENERATOR") @Column(name = "id") private BigDecimal id; @OneToMany(mappedBy = MST, orphanRemoval = true, cascade = { CascadeType.ALL}) @OrderBy("id DESC") private List<B> b = new ArrayList<B>(); @Column(name = "name") private String name; } When I modify class A'S SAY name attribute and say dao.persist(A) then onFlushDirty()[overridden in my Hibernate interceptor] is also invoked even if B object is not modified I am not understanding why hibernate is treating List<B> objects to be dirty when I am trying to save the parent object A Regards, Nitin MASTEK LTD.
