Deleted object would be re-saved by cascade (remove deleted object from associations)

Another workaround

I completely agree with redochka and Nikos Paraskevopoulos. Mahmoud Saleh's answer get over the issue in some circumstances not every time. In my situation I really need Eager fetchtype. So as Stony mentioned above I just removed from a list which cantian the object too. Here is my code:

Rju entity

public class Rju extends AbstractCompany implements Serializable {
    /**
     * 
     */
    private static final long serialVersionUID = 4294142403795421252L;


    //this field just duplicates @Column(name="callname") and serves for mapping to Rju fullname field
    @Column(name = "fullname")
    private String namerju;
    @NotEmpty
    @Column(name = "briefname")
    private String briefname;

    @LazyCollection(LazyCollectionOption.FALSE)
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "otd")
    private Collection<Vstan> vStanCollection;

//  @LazyCollection(LazyCollectionOption.FALSE)
    @OneToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL, mappedBy = "rju", orphanRemoval = true)
    private Collection<Underrju> underRjuCollection;
.........
}

Underrju entity

public class Underrju extends AbstractCompany implements Serializable {

    /**
     * 
     */
    private static final long serialVersionUID = 2026147847398903848L;


    @Column(name = "name")
    private String name;

    @NotNull
    @Valid
    @JoinColumn(name = "id_rju", referencedColumnName = "id")
    @ManyToOne(optional = false)
    private Rju rju;
......getters and setters..........
}

and my UnderrjuService

@Service("underrjuService")
@Transactional
public class UnderRjuServiceImpl implements UnderRjuService {

    @Autowired
    private UnderRjuDao underrjuDao;

    .............another methods........................
    @Override
    public void deleteUnderrjuById(int id) {
        Underrju underrju=underrjuDao.findById(id);
        Collection<Underrju> underrjulist=underrju.getRju().getUnderRjuCollection();
        if(underrjulist.contains(underrju)) {
            underrjulist.remove(underrju);
        }
        underrjuDao.delete(id);

    }
     .........................
}

I had the same exception, caused when attempting to remove the kid from the person (Person - OneToMany - Kid). On Person side annotation:

@OneToMany(fetch = FetchType.EAGER, orphanRemoval = true, ... cascade    = CascadeType.ALL)
public Set<Kid> getKids() {    return kids; }

On Kid side annotation:

@ManyToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "person_id")
public Person getPerson() {        return person;    }

So solution was to remove cascade = CascadeType.ALL, just simple: @ManyToOne on the Kid class and it started to work as expected.

Had the same error. Removing the object from the model did the trick.

Code which shows the mistake:

void update() {
    VBox vBox = mHboxEventSelection.getVboxSelectionRows();

    Session session = HibernateUtilEventsCreate.getSessionFactory().openSession();
    session.beginTransaction();

    HashMap<String, EventLink> existingEventLinks = new HashMap<>();
    for (EventLink eventLink : mEventProperty.getEventLinks()) {
        existingEventLinks.put(eventLink.getEvent().getName(), eventLink);
    }

    mEventProperty.setName(getName());

    for (Node node : vBox.getChildren()) {

        if (node instanceof HBox) {
            JFXComboBox<EventEntity> comboBoxEvents = (JFXComboBox<EventEntity>) ((HBox) node).getChildren().get(0);
            if (comboBoxEvents.getSelectionModel().getSelectedIndex() == -1) {
                Log.w(TAG, "update: Invalid eventEntity collection");
            }

            EventEntity eventEntity = comboBoxEvents.getSelectionModel().getSelectedItem();
            Log.v(TAG, "update(" + mCostType + "): event-id=" + eventEntity.getId() + " - " + eventEntity.getName());

            String split = ((JFXTextField) (((HBox) node).getChildren().get(1))).getText();
            if (split.isEmpty()) {
                split = "0";
            }
            if (existingEventLinks.containsKey(eventEntity.getName())) {
                // event-link did exist
                EventLink eventLink = existingEventLinks.get(eventEntity.getName());
                eventLink.setSplit(Integer.parseInt(split));
                session.update(eventLink);
                existingEventLinks.remove(eventEntity.getName(), eventLink);
            } else {
                // event-link is a new one, so create!
                EventLink link1 = new EventLink();

                link1.setProperty(mEventProperty);
                link1.setEvent(eventEntity);
                link1.setCreationTime(new Date(System.currentTimeMillis()));
                link1.setSplit(Integer.parseInt(split));

                eventEntity.getEventLinks().add(link1);
                session.saveOrUpdate(eventEntity);
            }

        }
    }

    for (Map.Entry<String, EventLink> entry : existingEventLinks.entrySet()) {
        Log.i(TAG, "update: will delete link=" + entry.getKey());
        EventLink val = entry.getValue();
        mEventProperty.getEventLinks().remove(val); // <- remove from model
        session.delete(val);
    }

    session.saveOrUpdate(mEventProperty);

    session.getTransaction().commit();
    session.close();
}

This problem will happen if you delete using PlaylistadMap modal instead of PlayList. In this case FetchType = Lazy is not the right option. It will not throw any exception but only data from PlaylistadMap will get deleted, the data in PlayList will remain in the table. Check that also.

I just to solve this problem.

1. I set to null the value of list
2. I saved the object (It worked)
3. I set the new data to the object
4. I resaved the object
5. It works.!

You need to remove association on the mapping object:

playList.getPlaylistadMaps().setPlayList(null);
session.delete(playList);

The Solution is to 'break' the relationship between the objects, and then try to delete again. The answer is in your log:

(remove deleted object from associations): [com.xeno.advertisingsuite.web.domain.PlaylistadMap#6]

Explain: what?(remove association) Where?[PlaylistadMap object with id#6]
