Form don't save

This is my php code

<?php include "../configurazione.php"; require_once('../../codebase_php/form_connector.php'); $connessione=mysql_connect(mysql_server, mysql_user, mysql_password); mysql_select_db("idea_comuni"); $form = new FormConnector($connessione); $form->enable_log("imballiform_php_log.txt"); $form->render_table("imballi","id","id,codice,descrizione"); ?>

Using form with dataprocessor we pass this data to the php file via get:

!nativeeditor_status: updated
codice: NYL
descrizione: PACKAGE NYLONchange
id: 1

Why the processor don’t update my data? The result of computation is:

<?xml version='1.0' encoding='utf-8' ?>

It seems that dataprocessor doesn’t recognize data update at all
Be sure that

a) connector.js included on the page and included after dataprocessor.js
b) you NOT changing data sending mode through dp.setTransactionMode
