Hey, all!
I'm starting with NHibernate, and I'm having some troubles with it.
Well, this is my
Code:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
    <class name="Ships.Domain.State, Ships.Domain" lazy="true" table="states">
        <id name="ID" column="HANDLE" type="Int64">
        </id>
        <property name="Name" column ="NAME" type="String" />
        <property name="Abreviation" column="ABREVIATION" type="String" />
    </class>
</hibernate-mapping>
This is my State POCO class:
Code:
namespace Ships.Domain
{
    public class State
    {
        public virtual long ID { get; set; }
        public virtual string Name { get; set; }
        public virtual string Abreviation { get; set; }


        public override string ToString() {
            return Name;
        }
    }
}

When I create a ISession object, I do it this way:
Code:
public ISession RetrieveSession()
{
    if (entidadeSessionFactoryCampus == null) {

        Configuration entidadeConfigurationCampus = new Configuration();
        entidadeConfigurationCampus.SetProperty("dialect", "NHibernate.Dialect.Oracle10gDialect");
        entidadeConfigurationCampus.SetProperty("connection.driver_class", "NHibernate.Driver.OracleClientDriver");
        entidadeConfigurationCampus.SetProperty("connection.connection_string", "/*My Connection String */");
        entidadeConfigurationCampus.AddAssembly("Ships.Domain");
        entidadeSessionFactoryCampus = entidadeConfigurationCampus.BuildSessionFactory();
    }
    return entidadeSessionFactoryCampus.OpenSession();
}
When I try to retrieve a collection, the NHibernate returns me nothing, a empty collection.
Code:
static void Main()
{
    ISession entidadeSession = NHibernateFactory.RetrieveSession();
    ICriteria entidadeCriteria = entidadeSession.CreateCriteria(typeof(State));
    IList ships = entidadeCriteria.List();
}


Anyone has any ideia about this problem?
Thanks all, God bless you!
