Hi,
I have a relationship manytoone like this:

Periodo---manytoone->dia----manytoone--->horario

when I save periodo, dia and horario do not save, and it does not throw and exception, it just doesn´t save.
this is my code:

In periodo class:

@OneToMany(fetch = FetchType.LAZY, mappedBy = "periodo", cascade=CascadeType.ALL)
@OrderBy("dia ASC")
public Set<Dia> getDias() {
return this.dias;
}

In Dia clasS:

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "periodo", nullable = false)
@NotNull
public Periodo getPeriodo() {
return this.periodo;
}

@OneToMany(fetch = FetchType.LAZY, mappedBy = "dia")
@OrderBy("inicio ASC")
public Set<Horario> getHorarios() {
return this.horarios;
}


in horario class:

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "dia", nullable = false, insertable=true, updatable=true)
@NotNull
public Dia getDia() {
return this.dia;
}



Any ideas??
