these mappings & criteria are identical to another parent/child
relationship that works fine just like this.
the Children collection is never populated.
am I missing something simple?
using (var session =
MyDataContext.Current.SessionManager.OpenSession())
{
using (var trans = session.BeginTransaction())
{
var cust =
session.CreateCriteria<TechSupportCustomer>()
.Add(nhc.Expression.Eq(rValue.NameOf(x =>
x.BillingInstanceID), customerBillingInstanceID))
.SetFetchMode(rValue.NameOf(x =>
x.ANsTNs), FetchMode.Eager)
.UniqueResult<TechSupportCustomer>();
// var cust =
session.Query<TechSupportCustomer>()
// .Where(x => x.BillingInstanceID ==
customerBillingInstanceID)
// .Single();
rValue = cust;
}
}

I actually use Fluent mappings ..
public CustomerChildMap()
{
base.Table("CUSTOMERS_CHILDREN");
base.Id(x => x.ID, Fields.ID)
.GeneratedBy.Sequence("SEQ_CUSTOMER_CHILDREN")
;
base.References(x => x.Customer)
.Column(Fields.CUSTOMER_ID)
.Not.Nullable()
;
}
public CustomerMap()
{
base.Table("CUSTOMERS");
base.Id(x => x.ID, Fields.ID)
.GeneratedBy.Sequence("SEQ_CUSTOMERS");
base.HasMany<CustomerChild>(x => x.Children)
.KeyColumn(CustomerChildMap.Fields.ID)
.Inverse()
;
}
