Autoload cache drivers

[quote author="Federico Biccheddu" date="1351098462"]Why doesn't work?

Code:

class MY_Controller extends CI_Controller {

function __construct()
{
  parent::__construct();

  $this->load->driver('cache', array('adapter' => 'file', 'backup' => 'file'));
}
}

On this class:

Code:

class Acl {

private $ci;

function __construct()
{
  $this->ci =& get_instance();

  if (!$foo = $this->ci->cache->get('foo'))
  {
   echo 'Saving to the cache!<br />';
   $foo = 'foobarbaz!';

   // Save into the cache for 5 minutes
   $this->ci->cache->save('foo', $foo, 300);
  }

  echo $foo;
}
}

(Acl is loaded by autoload.php)

Code:

A PHP Error was encountered

Severity: Notice

Message: Undefined property: Welcome::$cache

Filename: libraries/Acl.php

Fatal error: Call to a member function get() on a non-object in application\libraries\Acl.php on line 13

You can not use MY_Controller class __construct function in your library, you just need to load cache driver in your Acl library.
