Spring Boot Thyemeleaf Select Выберите значение раскрывающегося списка - java.lang.NumberFormatException

Question

У меня есть раскрывающийся список сущности " BusinessPartner ".

У меня есть все идентификаторы моих сущностей в виде строки и настроены " org.hibernate.id.UUIDGenerator «чтобы добавить префикс относительного события в мой идентификатор, например:« BPID_04a3e35b-12b3-447f-a982-338739e537f1 »

я получаю следующее исключение, когда пытаюсь перейти на страницу, содержащуюраскрывающийся список сущности "BusinessPartner".

Поиск по всему интернету для поиска решения, дайте мне знать, если кто-нибудь есть какие-либо подсказки.Я указал, где именно я получаю исключение в следующем фрагменте.

Java-версия: 1.8
Spring Boot Version: 1.5.10.RELEASE

Заказ сущности:

@Entity
@Table(name = Order.TABLE_NAME)
public class Order extends Model implements Serializable {
    @Enumerated(EnumType.STRING)
    @Column(name = DOCUMENT_TYPE)
    private DocumentType documentType;

    @Column(name = DOCUMENT_NUMBER, updatable = false)
    private String documentNumber;

    @Column(name = ORDER_DESCRIPTION)
    @NotEmpty
    private String orderDescription;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = COL_OTHER_PARTY_ID, nullable = false)
    private BusinessPartner otherParty;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = COL_AUTHORITY_BUSINESS_PARTNER_ID, nullable = false)
    private BusinessPartner authority;
}

BusinessPartner сущности:

@Entity
@Table(name = BusinessPartner.ENTITY_NAME)
public class BusinessPartner extends Model {
    @Column(name = NAME)
    private String name;

    @Column(name = EMAIL)
    private String email;

    // Getters and Setters omitted for simplicity
}

Родительская сущность:

@MappedSuperclass
public class Model {
    public static final String ID = "id";
    public static final String CREATED_AT = "createdAt";
    public static final String UPDATED_AT = "updatedAt";

    @Id
    @GeneratedValue(generator = "uuid")
    @GenericGenerator(name = "uuid", strategy = "com.emisha.database.Generators.IDGenerator")
    @Column(name = ID)
    private String id;

    @Version
    private Long version;

    @Column(name = CREATED_AT)
    private Date createdAt;

    @Column(name = UPDATED_AT)
    private Date updatedAt;

    public Model() {
        // Empty Constructor
    }

    /* DEFINED METHODS */
    @PrePersist
    protected void onCreate() {
        updatedAt = createdAt = new Date();
    }

    @PreUpdate
    protected void onUpdates() {
        updatedAt = new Date();
    }

    // GETTERS & SETTERS
}

Метод контроллера, который заполняет businessPartners:

public class OrderController extends EmishaAdminBaseController {

//.........
