Problem s FilterRoute chyba params[‚language‘]

Zdravim
mam nieco taketo:
bootstrap.php

<?php
	$frontRouter[] = $filterRoute = new Core\Application\Routers\FilterRoute("[!<language ([a-z]{2})>]/<id [a-z-]+>", array(
		'presenter' => 'Page',
		'action' => 'show',
		'language' => 'sk',
	));

	$filterRoute->addFilter('id', '\\Models\\PageModel::slugToId', '\\Models\\PageModel::idToSlug');
?>

PageModel.php

<?php
public static function idToSlug($id, \Nette\Application\Request $request)
    {

		$args = array('SELECT p.webalize
			FROM pages AS p
			JOIN [z_'.$request->params['language'].'] AS z ON p.title_dic_id=z.id
			WHERE z.id=%i', $id);
		$id = \dibi::query($args)->fetchSingle();

        return $id;
    }

	public static function slugToId($slug, \Nette\Application\Request $request)
    {
		$args = array('SELECT p.id
			FROM pages AS p
			JOIN [z_'.$request->params['language'].'] AS z ON p.title_dic_id=z.id
			WHERE z.webalize=%s', $slug);
		$id = \dibi::query($args)->fetchSingle();

		return $id;
    }
?>

BasePresenter.php

<?php
	/**
	 * @persistent
	 */
	public $language = 'sk';
?>

<?php
$this->link(':Front:Page:show', array('language' => 'sk', 'id' => 2));
//alebo
