listo, lo puede resolver configurando el fetch de la manytoone.
mapper.Class<Galeria>(x =>
{
x.ManyToOne(g => g.Linea, mpm =>
{
mpm.NotNullable(true);
mpm.Fetch(ConfOrm.Mappers.FetchMode.Join);
});
x.ManyToOne(g => g.Temporada, mpm =>
{
mpm.NotNullable(true);
mpm.Fetch(ConfOrm.Mappers.FetchMode.Join);
});
});
saludos

hola, tengo una aplicacion en un hosting llamado Dattatec, la aplicacion andaba

donde el problema es la generacion del proxy, seguramente la gente del hosting,
cambie los permisos a medium a trust o algo por el estilo.
parte del problema lo resolvi cambiando los Session.Load por Session.Get, pero
me quedo un solo lugar en una query que no evitar que se genere el proxy.
tengo estas 3 clases :
publicclass Temporada : Entity
{
public ISet<Galeria> Galerias { get; set; }
public virtual string Name { get; set; }
public virtual DateTime Creation { get; set; }
protected Temporada()
{
Galerias = new HashedSet<Galeria>();
}
public Temporada(string name):this()
{
Name = name;
}
public void AddGaleria(Galeria galeria)
{
Galerias.Add(galeria);
galeria.Temporada = this;
}
public void RemoveGaleria(Galeria g)
{
g.Temporada = null;
Galerias.Remove(g);
}
publicclass Galeria : Entity
{
public Linea Linea { get; set;}
public Temporada Temporada { get; set; }
private readonly IList<Imagen> imagenes;
public IEnumerable<Imagen> Imagenes
{
get
{
return imagenes;
}
}
internal Galeria()
{
}
public Galeria(Linea r)
{
Linea = r;
imagenes = new List<Imagen>();
}
public void AddImagen(Imagen img)
{
imagenes.Add(img);
}
public void AddImageRange(IList<Imagen> imgList)
{
foreach (var img in imgList)
{
imagenes.Add(img);
}
}
public void ClearImages()
{
imagenes.Clear();
}
public void RemoveImagen(Imagen img)
{
imagenes.Remove(img);
}
}
public class Linea : Entity
{
public virtual string Description { get; set; }
public Linea()
{
}
public Linea (string descripcion)
{
Description = descripcion;
}
}
les saque el virtual a las referencias y colecciones para evitar el Lazy..pero
con la siguiente query:
var criteria = sessionFactory.GetCurrentSession().CreateCriteria(typeof
(Temporada));
criteria.AddOrder(Order.Desc("Creation"))
.SetMaxResults(count);
return criteria.List<Temporada>();
la temporada y las galerias las trae bien, pero la referencia a Linea en las
instancias de galeria con proxies.
como puedo evitar que sea proxy ?
el mapping generado con ConfORM es :
<class name="Temporada">
<id name="Id" column="TemporadaId" type="Int32">
<generator class="hilo" />
</id>
<set name="Galerias" inverse="true" cascade="all,delete-orphan">
<key column="TemporadaId" on-delete="cascade" />
<one-to-many class="Galeria" />
</set>
<property name="Name" />
<property name="Creation" />
</class>
<class name="Linea">
<id name="Id" column="LineaId" type="Int32">
<genera tor class="hilo" />
</id>
<property name="Description" />
</class>
<class name="Galeria">
<id name="Id" column="GaleriaId" type="Int32">
<generator class="hilo" />
</id>
<many-to-one name="Linea" column="LineaId" not-null="true" />
<many-to-one name="Temporada" column="TemporadaId" not-null="true" />
<list name="Imagenes" access="field.camelcase" cascade="all">
<key column="GaleriaId" />
<list-index />
&a mp;nb sp; <one-to-many class="Imagen" />
</list>
</class>
disculpen la longitud del email!
gracias!
