Hello,
I have got a association object with a composite Id to resolve a
many-to-many association. The .KeyReference() part in the
CompositeId() leads to alot of selects which nhibernate performs
so load the entities.
Now I thought about mapping the columns twice. The id itself for
the KeyProperty and then adding a Reference for the property. But
nhibernate throws a "Index out of range exception" because it
tries to add a parameter to the sql insert command for the two
reference properties.
Instead of
CompositeId()
.KeyReference(x => x.Skill, f =>
f.Type<boSkillBase>(), "cat_occu_skill__id")
.KeyReference(x => x.Gruppe, f =>
f.Type<boSkillGruppeBase>(), "cat_occu_skill_group__id");
to
CompositeId()
.KeyProperty(x => x.SkillId, "cat_occu_skill__id")
.KeyProperty(x => x.GruppeId, "cat_occu_skill_group__id");
References(x => x.Gruppe)
.Fetch.Select()
.Column("cat_occu_skill_group__id")
.Class<boSkillGruppeBase>()
.Cascade.None();
References(x => x.Skill)
.Not.LazyLoad()
.Fetch.Select()
.Column("cat_occu_skill__id")
.Class<boSkillBase>()
.Cascade.None();
Is there any advice for this? Hm... at second thought this is not
really a fluent nhibernate question, but maybe someone is kind
enough to give me an advice?

Christan Erhardt
