Hello,
after correcting the issues arrising from the InverseManager, and adding
annotations to remove unlinked Entities (@ElementDependent) I get
an error due to duplicate key.
The goal is:
I have up to 5 Axles and the User can delete any one of them and the others
should
move up (Axle 3 becomes Axle 2 ...) When I delete the first Axel, I get an
exception.
I get all the axles back from the GUI and proceed to move them from the Data
Object
to my Entity:
TreeSet<AxleDTO> axleDtos = new TreeSet<AxleDTO>(new Comparator<AxleDTO>() {
@Override
public int compare(AxleDTO pO1, AxleDTO pO2) {
if (pO1.getAxleNumber() < pO2.getAxleNumber()) {
return -1;
} else if (pO1.getAxleNumber() == pO2.getAxleNumber()) {
return 0;
} else {
return 1;
}
}
});
axleDtos.addAll(pData.getAxles());
if (axleDtos != null && !axleDtos.isEmpty()) {
short i = 1;
Set<Axle> axles = new HashSet<Axle>();
AxleMgr axleMgr = new AxleMgr(mPm);
for (AxleDTO axleDto : axleDtos) {
Axle axle = new Axle();
axleMgr.toEntity(axleDto, axle);
if (!axle.isActive()) {
axle.setEquipmentId(null);
} else {
axle.setAxleNumber(i++);
axle.setEquipmentId(pEntity);
axles.add(axle);
}
}
pEntity.setAxles(axles);
}
@Entity
@Table(schema = "galaxy11", name = "Equipment")
public class Equipment extends BaseEntity {
@JsonManagedReference
@OneToMany(cascade = CascadeType.ALL, mappedBy = "equipmentId", fetch =
FetchType.EAGER)
@ElementDependent
private Set<Axle> axles = new HashSet<Axle>();
@Entity
@Table(schema = "galaxy11", name = "Axle", uniqueConstraints=
@UniqueConstraint(name="uq_Axle_equipmentId_axleNumber", columnNames = {
"equipmentId", "axleNumber" })
)
public class Axle extends BaseEntity {
@Basic
@Column(columnDefinition = "int2")
private short axleNumber;
@JsonBackReference
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "equipmentId", columnDefinition = "int8", nullable = false)
private Equipment equipmentId;
It all seems to work as I expect, except for the order of the statements!
The trace shows that the delete of the Axle is done AFTER the updates:

I am certain I am missing something quite minor, but after running interactive
debugs between
The GUI and the persistence for the last 48 hrs, I think I am missing the
obvious.
Anyone out there see where I am going astray?
Thanks,
John
