Hi all!
I tried to use a self referencing entity but unfortunately the deletion fails
with:
java.lang.IllegalStateException: java.lang.IllegalStateException:
org.hibernate.ObjectDeletedException: deleted object would be re-saved by
cascade (remove deleted object from associations): [PInstrument#1]
Using google I only found some samples using HBM files but I want to use
annotations. Is it necessary to declare both relations (manytoone and
onetomany)? I tried this also but without success.
please see the hibernate model class below:
@Entity
@Table(name = "INSTRUMENT")
public class PInstrument implements Serializable
{
@Id
@Column(name = "INSTRUMENT_ID")
@GeneratedValue(strategy = GenerationType.AUTO, generator =
"instrument_seq_gen")
@SequenceGenerator(name = "instrument_seq_gen", sequenceName =
"INSTRUMENT__SEQ")
private Long _id;
@Column(name = "NAME", unique = true, nullable = false, length = 50)
@NotNull
@Length(min = 2)
private String _name;
@ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
@OnDelete(action = org.hibernate.annotations.OnDeleteAction.CASCADE)
@Cascade({ org.hibernate.annotations.CascadeType.DELETE_ORPHAN,
org.hibernate.annotations.CascadeType.ALL} )
@JoinColumn(name="FK_INSTRUMENT_ID")
@Index(name = "IDX_FK_MAIN_INSTRUMENT")
private PInstrument _mainInstrument;
.... more attributes and set/get methods
}
I even added all possible cascade annotations, but the issue still remains. Any
hint is realy appreciated
Thanks in advance
jens
