Hi,
ich habe folgendes Problem.
Ich bekomme den oben genannten Fehler.
Ich weiß aber nicht warum.
Die beiden betroffenen Klassen sind Lecture und Appointment.
Hier der Mapping Ausschnitt aus Lecture:
Code:
@OneToMany(fetch=FetchType.LAZY, mappedBy="lecture")
private List<Appointment> appointments = new ArrayList<Appointment>(0);
Hier der Mapping Ausschnitt aus Appoitnment:
Code:
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="lecture", nullable=false)
private Lecture lecture;
Die NamedQuery für FIND_ALL_LECTURES sieht wiefolgt aus:
Code:
FROM Lecture
Woher kann dieser Fehler kommen?
Bei allen andern OneToMany Mappings (auch als List) funktioniert es.
Danke im Voraus.
Gruß
