The Business entity is automapped, but I use an override to handle
several desired changes, such as cascading, and many-to-many mapping.
Since the HasMany wasn't getting automapped correctly, I tried to
override it, but still no luck.
public class BusinessMap : IAutoMappingOverride<Business> {
public void Override(AutoMap<Business> mapping) {
mapping.JoinedSubClass<Manager>("BusinessId")
.HasManyToMany<Customer>(x => x.Customer)
... // excluded for brevity
// Does not work correctly
mapping.JoinedSubClass<Manager>("BusinessId")
.HasMany(x => x.ManagedCustomers)
.KeyColumnNames.Add("PrimaryManagerFk")
.Inverse();
}
}
The automapping gets the forward mapping right (i.e.,
mapping.JoinedSubClass<customer>("BusinessId").References<Manager>(x
=> x.PrimaryManager)), but not the reverse, always using the wrong key
column.
Thanks for helping.
