Troubles with __destructor

[eluser]@l1[/eluser]
Hi to all! I'm just start to learn CodeIgniter, and meet some trouble that seems to be a bug.
After reading manual section about views I conclude that CodeIgniter has not "magic loading" views per controler/action like it work in Zend or Cake etc. So i try to make it. First of all i load "layout library" and some customize it. Then, i create __destruct() in my Index controler(almost full copy of welcome controller).

Here it is:

Code:

<?php  
if (!defined('BASEPATH')) exit('No direct script access allowed');

class Layout {
    
    private $obj;
    private $layout;
    private $controller;
    private $action;
    
    public function __construct($layout = "layouts/layout") {
        $this->obj =& get_instance();
        $this->layout = $layout;
        $this->controller = $this->obj->router->class;
        $this->action = $this->obj->router->method;
    }

    public function setLayout($layout) {
        $this->layout = $layout;
    }
    
    public function view($view = false, $data = null, $return = false) {
        $this->obj->is_rendered = true;
        
        if (!$view)
            $view = $this->action;

        $loadedData = array();
        $loadedData['content_for_layout'] = $this->obj->load->view($this->controller . '/' . $view, $data, true);
        if ($return) {
            $output = $this->obj->load->view($this->layout, $loadedData, true);
            return $output;
        } else {
            $this->obj->load->view($this->layout, $loadedData, false);
        }
    }
    
    public function setData($data = null) {
        $this->view(false, $data);
    }
}
?>

Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Index extends CI_Controller {
    
    public $is_rendered = false;

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

    public function index() {
        //$this->layout->setData(array('hello' => 'HELLO'));
    }
    
    public function hello() {
        $this->layout->view('hello');
    }    
    
    public function __destruct() {
        if (!$this->is_rendered) {
            $this->layout->view(false, array('hello' => 'HELLO'));
        }
    }
}

So when i try to call index action of index controller with settingData($this->layout->setData(array('hello' => 'HELLO')) all working good, but if i comment this line, appear warnings:


Warning: include(application/errors/error_php.php) [function.include]: failed to open stream: No such file or directory in F:\www\htdocs\local.example.com\system\core\Exceptions.php on line 167

Warning: include() [function.include]: Failed opening 'application/errors/error_php.php' for inclusion (include_path='.;C:\php5\pear') in F:\www\htdocs\local.example.com\system\core\Exceptions.php on line 167

Warning: include(application/errors/error_php.php) [function.include]: failed to open stream: No such file or directory in F:\www\htdocs\local.tendy.com\system\core\Exceptions.php on line 167

So i fix it by setting include path:

Code:

set_include_path(get_include_path() . ';' . dirname(__FILE__) . '/../../');

And after that i have next error:

An Error Was Encountered
Unable to load the requested file: index/index.php

When i debug it, i found that error here:

Code:

if ( ! file_exists($_ci_path))

system/core/Loader.php line #637

I understand that it can be fixed by adding something like

Code:

if ( ! file_exists(dirname(__FILE__) . '/../../' . $_ci_path))

But after fixing this things in other places i have a clean screen output without my layout or view script

P.S. Sorry for my english.
