Bien segun lo tengo entiedo que yo al obtener un producto (pto) obtendria el tipo al que pertenece de la siguiente manera pto.getTipo_Id(), esto me devolvera un objeto de la clase tipoProducto. Bien PORQUE NO LO HACE.

A una puntualizacion al insertar un producto nuevo y asignarle un tipo producto inserta perfectamente el ide del tipo producto en la base de datos.

Un saludo y muchas gracias por anticipado.
