I have done many database view to get simply select

Does phpgrid has problems adding records to database views if they are made with many tables.

ex:view: V3matematica

SELECT alumno.apellido as Apellido,
alumno.nombre as Nombre,
nota.calificacion as Calificacion,
nota.id_conducta as Conducta,
nota.observaciones as observaciones
FROM nota, alumno, evaluacion, materia
WHERE nota.id_alumno = alumno.id and
nota.id_evaluacion = evaluacion.id AND
evaluacion.id_materia = materia.id and
materia.id=388 AND
evaluacion.id_tipo_evaluacion= 3

this is the select of the view.

The code on mi wordpress is [phpgrid table="v3matematica1" edit="true" caption="Primer" export="true" language="es"]

I looks well but i cannot edit or add rows!
