Hi,

I'm new to nhibernate and I think I will heavily use it in the very near future. Now I'm playing with the examples. But I have a problem...

this is the code I use:
fiu(Romanian)=son(English)
mama(Romanian)=mother(English)

Code:

ClassLibrary1.Cat mama=new ClassLibrary1.Cat();
mama.Name="mama";
mama.Birthdate=DateTime.Now;

ClassLibrary1.Cat fiu1=new ClassLibrary1.Cat();
fiu1.Name="fiu1";
fiu1.Birthdate=DateTime.Now;

ClassLibrary1.Cat fiu2=new ClassLibrary1.Cat();
fiu2.Name="fiu2";
fiu2.Birthdate=DateTime.Now;

ClassLibrary1.Cat fiu3=new ClassLibrary1.Cat();
fiu3.Name="fiu3";
fiu3.Birthdate=DateTime.Now;

mama.Kittens=new Iesi.Collections.HashedSet();
mama.Kittens.Add(fiu1);
mama.Kittens.Add(fiu2);
mama.Kittens.Add(fiu3);
                
session.Save(mama);

Basically I want a cat with a few sons and when the mother is saved I want the mother_id from each son to be seted correctly. But this is not happening... :(( mother_id is NULL for every son

the mapping xml:

Code:

<?xml version="1.0" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
    <class name="ClassLibrary1.Cat, ClassLibrary1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" table="CATS">
        <id name="Id" column="uid" type="Int64">
            <generator class="identity"/>
        </id>
        <property name="Birthdate" type="Date"/>
        <property name="Sex" not-null="true" update="false"/>
        <property name="Weight"/>
        <property name="Name"/>
        <many-to-one name="Mate" column="mate_id"/>
        <set name="Kittens" cascade="all">
            <key column="mother_id"/>
            <one-to-many class="ClassLibrary1.Cat, ClassLibrary1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
        </set>
    </class>
</hibernate-mapping>

What am I missing?
