Nefunkční komponeta v podřízeném presenteru

Ahoj, nefunuguje mi formulář v presenteru, který se volá z nadřazeného presenteru. Když přesunu metodu createComponentGuestbookForm do DefaultPresenteru, tak mi vše funuje správně.

DefaultPresenter:

<?php

namespace App\FrontModule\Presenters;

class DefaultPresenter extends BasePresenter
{

    public function renderPage($seo_url_text)
    {
        $this->template->modules = $this->loadModules();
        $url_array = array_reverse(explode("/",$seo_url_text));
        $this->template->catId = (int)$url_array[0];
    }
}
?>

v template guestbooku mám:

<div class="module-inner">
    <h3 id="guestBook{$moduleId}">Diskuzní knihahhh</h3>

    {control guestbookForm}

    <div n:foreach="$guestBookPosts as $post">
            <h4 class="media-heading">{$post->name} • {$post->email} • <span class="datetime">{$post->timestamp}</span></h4>
            <p>{$post->text}</p>
    </div>
    <div class="clearboth"></div>
</div>

Prosím poradte mi, kde je chyba.
