Actually I think I solved the problem by using the relationship keypath in the
qualifier:
if ( cd.toOneRelationshipKeys().contains(sv1)) {
EORelationship relation1 = entity.relationshipNamed(sv1);
v1Qual= new EOKeyValueQualifier(relation1.relationshipPath(),
EOQualifier.QualifierOperatorEqual, record);
}
NSArray objectsInRow = EOQualifier.filteredArrayWithQualifier(relevantObjects,
v1Qual);
That seems to work.

Instead of calling classe().lycée(), I can just call lycée().
It is also useful to me because I I dynamically present the relations to the
user for selection in a popup menu. So I need a direct relationship to Lycée.

Because I build different qualifiers if the relationship is a to-many (I didn't
show it in the code I sent, because it is not relevant).

You are right, but this is D2W app, and I thought it would save me writing a
lot of displayNameForProperty rules.
Thanks for your reply
