Hello Tom,
AFAIK it is that simple:
class Sojourn {
// ...
/** Set of sorted references to tour-stops that take place at this sojourn. Please remind that these are also part of a tour. */
@OneToMany(cascade = {CascadeType.PERSIST, CascadeType.DETACH, CascadeType.REFRESH, CascadeType.REMOVE, CascadeType.MERGE}, fetch = FetchType.LAZY, mappedBy = "sojourn")
@JoinFetch(value=JoinFetchType.OUTER)
private Set<SojournPosition> positions;
/**
* Creates a SojournPosition that references the given TourPosition and inserts it to the set of psoitions.
*/
public SojournPosition addTourPosition (int index, TourPosition s) {
if (index < 0)
throw new IllegalArgumentException (String.format ("Value %d for index is too small.", index));
List<SojournPosition> sorted = getPositionsBySeq ();
if (index > sorted.size ())
throw new IllegalArgumentException (String.format ("Value %d for index is too big.", index));
if (index == sorted.size ()) {
if (positions == null) positions = new HashSet<SojournPosition>();
SojournPosition sp = new SojournPosition (this, s, index);
positions.add (sp);
return sp;
} else {
SojournPosition sp = new SojournPosition (this, s, index);
List<SojournPosition> positions = getPositionsBySeq();
for(int i = index; i < positions.size(); i++){
SojournPosition tempPos = positions.get(i);
tempPos.setIndex(tempPos.getIndex() + 1);
}
positions.add (sp);
return sp;
}
}
}
class SojournPosition {
// ...
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="sojourn_id", nullable=false)
@ForeignKey(onDelete=ForeignKeyType.CASCADE, onUpdate=ForeignKeyType.RESTRICT) // That's an annotation of our own.
private Sojourn sojourn;
}

Betreff: Re: [eclipselink-users] During synchronization a new object was found through a relationship that was not marked cascade PERSIST:
You are correct (the key here is the lack of a cascade to a related object). Is
your failing example that simple?

Hello Tom,
but isn't that what CascadeType.PERSIST is mentioned to do?
In the example given: If the instance of B referenced in A was marked cascade=CascadeType.PERSIST in A. Then I expect that this instance of B is persisted by EL, without a extra call of em.persist().
Am I wrong?

Betreff: Re: [eclipselink-users] During synchronization a new object was found through a relationship that was not marked cascade PERSIST:
This exception indicates that there is a non-managed object related to an object
that is managed.
e.g. You have a relationship between A and B without cascade persist. You
create an A, related it to a B and then persist the A without persisting the B.

Hello,
I've got the exception mentioned in the subject although the relation is
marked cascade PERSIST.
Any ideas what might cause this?
Is this a known bug?
We're using EL 2.1.3
Kind Regards,
Michael Simons
