Also, the To Be Stored entity must implements Serializable interface, and
its methods: serialize, unserialize.
If you are unfamiliar to it, this is an example:
class Producto implements \Serializable
{
$id;
$nombre;
$descripcion;
$cantidad;
$categoria;
public function serialize()
{
$data = array('id' => $this->id, 'nombre' => $this->nombre,
'descripcion' => $this->descripcion,
'cantidad' => $this->cantidad, 'precio' => $this->precio,
'categoria' => $this->categoria);
return serialize($data);
}
public function unserialize($serilized)
{
$data = unserialize($serilized);
$this->id = $data['id'];
$this->nombre = $data['nombre'];
$this->descripcion = $data['descripcion'];
$this->cantidad = $data['cantidad'];
$this->precio = $data['precio'];
$this->categoria = $data['categoria'];
}
#here goes Getters and Setters
}

>> Hi,

>> }
>>
>> return $this->forward('ClubUserBundle:AdminUser:index');

>>
>> Pretty straight forward, and when i want to load the form i simple
