Config Item Not Working On Hooks

Hello I am not sure what I have done wrong with my Hooks

On any other controller if I use $this->config->item('maintenance') or config_item('maintenance')

It returns the correct value 1 if maintenance mode on or 0 for off.

How ever when I try to load it into my hook with $this->CI->config->item('maintenance') or config_item('maintenance')

It does not work. Any suggestion on how to be able to use config item in hooks?

Hook

PHP Code:

<?php

class Preaction {

    public function __construct() {
        $this->CI =& get_instance();
    }

    public function check() {
        echo config_item('maintenance');

        //if (config_item('maintenance')) {
        //    echo "On";
       // } else  {
       //     echo "Off";
        //}
    }
} 


PHP Code:

$hook['pre_controller'] = array(
        'class'    => 'Preaction',
        'function' => 'check',
        'filename' => 'Preaction.php',
        'filepath' => 'hooks'
); 


There's only one rule - please don't tell anyone to go and read the manual.  Sometimes the manual just SUCKS!

config_item() should work.

get_instance() can't work before a controller is instantiated.

When I use config_item('maintenance') it seems to only work with post_controller and not pre_controller

Something else is wrong, not config_item(). CI itself uses this function even before 'pre_system'.

In stead of creating a library to set a config item. At the bottom of my config.php file I now do this

PHP Code:

require_once (BASEPATH . 'database/DB.php');
$db =& DB();

$query = $db->get('setting');

foreach ($query->result_array() as $result) {
    $config[$result['key']] = $result['value'];
} 


And then when I use this config_item('maintenance') it now full works fine.
