Could you provide a little more information or recreation steps to help debug?

This is my controller

<?php
require_once(FUEL_PATH.'/libraries/Fuel_base_controller.php');

class example1 extends Fuel_base_controller {
public $nav_selected = 'example1';

function __construct()
{
parent::__construct();
$this->config->module_load('example1', 'example1');
$this->_validate_user('example1');
}

function index()
{
$this->load->module_model(EXAMPLE_FOLDER, 'example');
$this->js_controller_params['method'] = 'add_edit';

$field_values = $this->example->find_all_array_assoc('number');

if (!empty($_POST['example1']))
{
// format data for saving
$save = array();
foreach($field_values as $field => $value)
{
$example1 = $this->input->post('example1', TRUE);
$val = (isset($example1[$field])) ? $example1[$field] : '';
$save[] = array('number' => $field, 'value' => trim($val));
}
$this->example->save($save);
$this->session->set_flashdata('success', lang('data_saved'));
redirect($this->uri->uri_string());

}

$this->load->library('form_builder');

$fields = array();
$fields['number'] = array();
$fields['date'] = array();
$fields['time'] = array();
$fields['invoiceno'] = array();
$fields['invoicedate'] = array();

$this->form_builder->label_layout = 'left';
$this->form_builder->form->validator = &$this->example->get_validation();
$this->form_builder->use_form_tag = FALSE;
$this->form_builder->set_fields($fields);
$this->form_builder->display_errors = FALSE;
$this->form_builder->name_array = 'example1';
$this->form_builder->submit_value = 'Save';
$this->form_builder->set_field_values($field_values);


$vars = array();
$vars['form'] = $this->form_builder->render();
a$vars['warn_using_config'] = !$this->config->item('blog_use_db_table_settings');

$this->_render('example1', $vars);

}

}

What is the URI to this page and do you have a route in place for it? Is it at least getting to the constructor method?
