Re: Problem relationship with 2 eomodels

I found the way to make it work in awakeFromFetch of EntityBFromModel1.
 I had to set the id used for the to-one relationship in the class and I was
abled to fetch the corresponding EntityCFromModel2 :

    public void awakeFromFetch(EOEditingContext ec)
    {
      EntityCFromModel2 entC =
(EntityCFromModel2)EOUtilities.objectWithPrimaryKeyValue(ec,"EntityCFromModel2",
idForRelation());
    }

better idea ?
