in my entity I have the following annotation. I have generated the entities with DALI_0.5:
---------------BEGIN----------------------
@Entity
public class Stoerung implements Serializable {
@EmbeddedId
private Stoerung.PK pk;
...

private Aggregat nameaggregat;


@ManyToOne
@JoinColumns({
@JoinColumn(name="NAMEANLAGENTEIL", referencedColumnName="NAMEANLAGENTEIL"),
@JoinColumn(name="NAMEAGGREGAT", referencedColumnName="NAMEAGGREGAT")
})
private Anlagenteil anlagenteil;
.
.
.
.
----------------ENDE-------------------

the entity with the FK is the following:

------------ BEGIN------------------------
@Entity
public class Anlagenteil implements Serializable {
@EmbeddedId
private Anlagenteil.PK pk;

@ManyToOne
@JoinColumn(name="NAMEAGGREGAT")
private Aggregat nameaggregat;

@OneToMany(mappedBy="anlagenteil")
private Set stoerungCollection;

private static final long serialVersionUID = 1L;

public Anlagenteil() {
super();
}

public Anlagenteil.PK getPk() {
return this.pk;
}

public void setPk(Anlagenteil.PK pk) {
this.pk = pk;
}

public Aggregat getNameaggregat() {
return this.nameaggregat;
}

public void setNameaggregat(Aggregat nameaggregat) {
this.nameaggregat = nameaggregat;
}

public Set getStoerungCollection() {
return this.stoerungCollection;
}

public void setStoerungCollection(Set stoerungCollection) {
this.stoerungCollection = stoerungCollection;
..
..
..

and the exception is:
