OK, then I did replace all ISet<> with HashSet<>. Also, commented the
collection factory line.
The configuration passes, on save, I get the following error:
{"Unable to cast object of type
'NHibernate.Collection.Generic.PersistentGenericSet`1[FluentNHSampleApp.Domain.Customization]'
to type
'System.Collections.Generic.HashSet`1[FluentNHSampleApp.Domain.Customization]'."}
Relevant classes (skipping EntityBase that keeps the Id):
public class Product : EntityBase
{
private readonly HashSet<Customization> customizations;
public Product()
{
customizations = new HashSet<Customization>();
}
public virtual string Name { get; set; }
public virtual decimal Price { get; set; }
public virtual HashSet<Customization> Customizations
{
get { return customizations; }
}
}
public class Customization : EntityBase
{
private readonly HashSet<string> possibleValues;
public Customization()
{
possibleValues = new HashSet<string>();
}
public virtual string Name { get; set; }
public virtual HashSet<string> PossibleValues
{
get { return possibleValues; }
}
}
Supposedly relevant generated XML mapping:
<set access="nosetter.lowercase" cascade="all"
name="Customizations"> <key> <column name="Product_id" />
</key> <one-to-many
class="FluentNHSampleApp.Domain.Customization, FluentNHSampleApp,
Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" /> </set>
Here is what the Save code looks like (copy paste from Jose's orking confORM
example):
using (ITransaction tx = s.BeginTransaction())
{
var product = new Product
{
Name = "Fideos",
Customizations =
{
new Customization
{
Name = "Tuco",
PossibleValues =
{"Pocon", "Medio", "Sopa"}
}
}
};
s.Save(product);
tx.Commit();
}
Any ideas? Thanks again.
