Сетка Ваадина Неправильный выбор

В данный момент я пишу приложение Vaadin, и у меня проблема с выбором сетки. Если я сначала редактирую элемент, а затем удаляю его, я получаю исключение.

org.springframework.orm.jpa.JpaObjectRetrievalFailureException: невозможно найти com.mmm.inventur.data.StockAtLocation с идентификатором 252; вложенным исключением является javax.persistence.EntityNotFoundException: невозможно найти com.mmm.inventur.data.StockAtLocation с идентификатором 252 в org.springframework.orm.jpa.EntityManagerFactoryUtils.convertJpaAccessExceptionIfPossible(EntityManagerFactoryUtils.java:389) ~[spring-orm-4.3 .13.RELEASE.jar:4.3.13.RELEASE] в ...

если я сначала отменю выбор элемента и удалю его, все будет работать отлично.

Элемент, который я редактирую, является экземпляром статьи, он содержит несколько объектов StockAtLocation, редактируя экземпляр статьи, я удаляю StockAtLocation из набора, а также из объекта статьи.

@Entity
@Getter
@Setter
public class Article implements Serializable {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(nullable = false, unique = true)
private Long id;
@Column(nullable = true, unique = true)
private Long carlaId;
@Column(nullable = true, unique = true)
private Long ean;
@Column(nullable = false, unique = false)
private String name;
private String descr;

@Column(nullable = false)
@OneToMany(mappedBy = "article", cascade = CascadeType.ALL)
private List<StockAtLocation> stocks;


public Article() {
    stocks = new ArrayList<>();
}

public int getCompleteCntStock() {
    int re = 0;
    for (StockAtLocation stock : stocks) {
        re += stock.getCntStock();
    }
    return re;
   }

public int getCompleteOldStock() {
    int re = 0;
    for (StockAtLocation stock : stocks) {
        re += stock.getOldStock();
    }
    return re;
}
}

@Entity
@Getter
@Setter
public class StockAtLocation implements Serializable {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(nullable = false, unique = true)
private Long id;

private String stockArea;
private Timestamp lastModify;
private String note;
private int oldStock;
private int cntStock;

@ManyToOne(cascade = CascadeType.PERSIST, optional = true)
private Device modifiedBy;

@JoinColumn(nullable = false)
@ManyToOne(optional = false, cascade = CascadeType.PERSIST)
private StorageLocation storageLocation;

@ManyToOne
private Article article;

}

Там выбрасывается исключение

@Service
public class ArticleService {

@Autowired
private ArticleRepository articleRepo;

public void save(final Article article) {
    this.articleRepo.save(article);
}

@Transactional
public void deleteArticle(final Article delete) {
    try {
        this.articleRepo.delete(delete);
    } catch (JpaObjectRetrievalFailureException e) {
        // right here the exception occurs
        throw e;
    }
}

действие удаления статьи

this.btnDelete.addClickListener(new Button.ClickListener() {
        @Override
        public void buttonClick(Button.ClickEvent event) {
            for (Article selectedItem : articleGrid.getSelectedItems()) {
                    arService.deleteArticle(selectedItem);

            }
            dataProvider.refreshAll();
            articleGrid.deselectAll();
        }
    });

действие удаления StockAtLocation

private Article modified;
@Override
public void buttonClick(Button.ClickEvent event) {
    // store changes in the database
    Set<StockAtLocation> selectedItems = stockGrid.getSelectedItems();
    stockGrid.deselectAll();
    modifyCallBack.deleteStocks(modified, selectedItems);
    // update the grid
    stockGrid.setItems(modified.getStocks());
}

изменитьCallBack

(deleteFrom, delete) -> {
     if (deleteFrom.getStocks().isEmpty()) {
         return;
     } else if (!deleteFrom.getStocks().removeAll(delete)) {
         throw new Error("removing does not work!");
     }
     stockService.delete(delete);
     dataProvider.refreshItem(deleteFrom);
 });
