Getting rid of this property doesn't solve my problem.
My listener:
@Singleton
public class MultiLangStringEntityListener {
@PostLoad
@SuppressWarnings("UseSpecificCatch")
public void postLoad(Object entity) {
An entity:
@Entity
@EntityListeners({MultiLangStringEntityListener.class})
@Table(name = "THEME")
@XmlRootElement(name = "Theme")
@NamedQueries({
@NamedQuery(name = "DmTheme.findAll", query = "SELECT d FROM DmTheme d")})
public class Theme implements Serializable {
private static final long serialVersionUID = 1L;
// @Max(value=?) @Min(value=?)//if you know range of your decimal fields
consider using these annotations to enforce field validation
@Id
@Basic(optional = false)
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "SEQ_THEME")
@SequenceGenerator(name = "SEQ_THEME", sequenceName = "SEQ_THEME",
allocationSize = 1)
@Column(name = "ID")
private BigInteger id;
@Embedded
@AttributeOverrides({
@AttributeOverride(name = "id", column = @Column(name = "DESCR",
nullable=false)),
@AttributeOverride(name = "lang", column = @Column(insertable = false,
updatable = false, name = "DESCR")),
@AttributeOverride(name = "text", column = @Column(insertable = false,
updatable = false, name = "DESCR"))
})
private MultiLangString descr;
The embeddable class:
@Embeddable
public class MultiLangString implements Serializable {
private static final long serialVersionUID = 1L;
private String id;
private String lang;
private String text;
public MultiLangString() {
}
Some of my entity classes use both @Embedded and @EmbeddedId but not on the
same field. I don't know what is wrong as it still works with Hibernate whereas
I try to stay far from its specific features as you can see in this bug report:
