[fw-general] Smarty integration

[highland]

Hello

I  created my own class extending Zend_View_Abstract and including smarty.
I wanted to be able to use smarty templates and zend render on the same
object. 
Here is my code:
<?php
class MyView extends Zend_View_Abstract
{
    private $_smarty = false;
    
    public function __construct($data = array())
    {
        parent::__construct($data);
        
        $config = Zend::registry('config');
        
        $this->_smarty = new Smarty();
        
        $main_path = $config->path->server.$config->path->homepage;     
        $this->_smarty->template_dir =
$main_path.$config->smarty->template_dir;       
        $this->_smarty->compile_dir =
$main_path.$config->smarty->compile_dir;
        $this->_smarty->config_dir = $main_path.$config->smarty->config_dir;
        $this->_smarty->cache_dir = $main_path.$config->smarty->cache_dir;
    }
    
    protected function _run($template=null)
    {       
        print parent::render($template);
    }

    public function display($template)
    {
        $this->_smarty->display($template);
    }
    
    public function assign($var, $value=null)
    {
        if (is_string($var))
        {
            $value = @func_get_arg(1);
            
            $this->_smarty->assign($var, $value);
        }
        elseif (is_array($var))
        {
            foreach ($var as $key => $value)
            {
                $this->_smarty->assign($key, $value);
            }
        }
        else
        {
            throw new Zend_View_Exception('assign() expects a string or
array, got '.gettype($var));
        }
    }
    
    public function escape($var)
    {
        if (is_string($var))
        {
            return parent::escape($var);
        }
        elseif (is_array($var))
        {
            foreach ($var as $key => $val)
            {
                $var[$key] = $this->escape($val);
            }

            return $var;
        }
        else
        {
            return $var;
        }
    }
    
    public function output($name)
    {
        header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
        header("Cache-Control: no-cache");
        header("Pragma: no-cache");
        header("Cache-Control: post-check=0, pre-check=0", FALSE);

        print parent::render($name);
    }
    
    public function render($name)
    {
        header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
        header("Cache-Control: no-cache");
        header("Pragma: no-cache");
        header("Cache-Control: post-check=0, pre-check=0", FALSE);

        print parent::render($name);
    }
    
    public function isCached($template)
    {
        if ($this->_smarty->is_cached($template))
        {
            return true;
        }
        
        return false;
    }

    public function setCaching($caching)
    {
        $this->_smarty->caching = $caching;
    }
}
?>

in Controller for drawing using smarty i use:
$view->display('smarty_template.tpl')
and it works fine. But i want also to be able to use on the same $view
object
Zend render (so i could process php code), so i tried:
$view->render('zend_template.tpl.php')

But Zend returned:
Zend_View_Exception: script './application/views/zend_template.tpl.php' not
found in path in /usr/share/php/Zend/View/Abstract.php on line 571

Why ? How can i correct it ?

Thanx
