I receive the exception
Index was out of range. Must be non-negative and less than the size of the collection
when i try to SaveOrUpdate
a Bsa object. I think the problem is that i map the same row twice, once as a property and once as a List of children.
public BsaMap()
{
Schema("MYS");
Table("BSA");
Id(x => x.Id, "BSA_S").GeneratedBy.TriggerIdentity();
HasMany(x => x.BitTypeList).KeyColumn("BSA_S").Fetch.Subselect().Inverse().Not.LazyLoad().Cascade.SaveUpdate();
}
One Bsa has many BitTypes, and each BitType got the BSA_S as its foreign key. How should i map this, to avoid the error? I like having the I'd like to keep the BSA_S as a property field.
Any advice?
Found the problem. In The BitType entity, i had mapped BSA_S twice, one as:
Map(x => x.BsaS).Column("BSA_S");
and:
References(x => x.Parent).Column("BSA_S").Cascade.None().Not.LazyLoad().Not.Nullable();
