[PHP]$_GET nie odpowiada Opcje

[emeres1]

witam,
to moj kontroller index:

[PHP] pobierz, plaintext 
<?php
class App_Controller_Guest_Index extends Lib_Template_Page {
    function __construct(){
		$_SESSION['state']="";
		$this->owner= Lib_State_Owner::getOwner($_GET['value'],$_SESSION['state']);
 
       if (empty($_GET['controller'])){ $_GET['controller'] = 'index';} else {  $_GET['controller'];};
       if (empty($_GET['action'])){ $_GET['action'] = 'index';}
       echo  $_GET['subpage'];
 
    }
    public function indexAction(){
 
        $content = Lib_Factory_Controller::getController($_GET['controller'],$_GET['action']);
 
        //$action = Lib_Factory_Final::finalUrl($_GET['controller'],$_GET['action'],$this->langueState);
        $this->content = $content->run($_GET['action']);
        include_once('app/view/layout.phtml');
 
    }
 
}
?>

to klasa która wywołuje linkiem np.index.php?controller=login&subpage=login:

[PHP] pobierz, plaintext 
<?php
class App_Controller_Guest_Login extends Lib_Template_Subpage{
 
    public function  indexAction(){
    $model= new App_Model_Guest_Login();
	echo $_GET['subpage'];
	if($_GET['subpage'] == 'login'){
	$login = $model->login($_POST['login'].$_POST['pass']);
	echo $_POST['login'];
	}elseif ($_GET['move']=='logout'){
	$logout = $model->logout();
	}
 
    }
}
 
?>
[PHP] pobierz, plaintext 

Jaki może być powód tego ,że po wywołąniu kontrolera "login" wartość $_GET['subpage'] jest pusta.W klasie kontorolera "index" nie ma problemu?

pozdrawiam
