Nefunguju flashmessage pri redirect

Robim na modularnej app v PHP 5.3. Postupujem celkom dobre, ale teraz som zistil, ze na backende (ale aj frontenede) mi nejdu flashmessage ak kdekolvek (presenter, form callback) pouzijem $this->redirect(). Ak dam nastavenie flashmessage do akcie presentera, tak to funguje.

Celu app som v podstate vystaval na skeletone, prihlasovanie som spravil podla akrabat. V akrabate to beha krasne, v mojej app nie.

<?php
// glob. namespace
use Nette\Application\Presenter;

abstract class BasePresenter extends Presenter
{
    public $oldLayoutMode = FALSE;
    public $oldModuleMode = FALSE;

}
?>

<?php
namespace AdminModule;
use Nette\Environment;

class BasePresenter extends \BasePresenter
{

    protected function beforeRender()
    {
        $user = Environment::getUser();
        $this->template->user = ($user->isAuthenticated()) ? $user->getIdentity() : NULL;
    }

}
?>

<?php
namespace AdminModule;

use Nette\Environment;
use Nette\Web\User;

class DashboardPresenter extends BasePresenter
{
    protected function startup()
    {
        $user = Environment::getUser()->setAuthorizationHandler(new \Srigi_Acl());

        if (!$user->isAuthenticated()) {
            if ($user->getSignOutReason() === User::INACTIVITY) {
                $this->flashMessage('You have been logged out due to inactivity. Please login again.');
            }

            $backlink = $this->getApplication()->storeRequest();
            $this->redirect('Auth:login', array('backlink' => $backlink));

        } else {

            // only ADMIN or ROOT can access Presenter
            if (!$user->isAllowed($this->reflection->name, $this->getAction())) {
                $this->flashmessage('Na vstup do admin sekcie nemáte dostatočné oprávnenia!'); // nejde
		$this->redirect('Auth:login');
            }

        }

        parent::startup();
    }


    public function actionDefault()
    {

    }


    public function actionLogout()
    {
        Environment::getUser()->signOut();
        $this->flashMessage('You have been logged off.'); // nejde
        $this->redirect('Auth:login');
    }
}
?>

<?php

    public $backlink = '';


    protected function createComponentLoginForm($name)
    {
        $form = new AppForm($this, $name);

        $form->addText('login', 'Email:')
             ->addRule(Form::EMAIL, 'Prosím zadajte registračný email.');

        $form->addPassword('password', 'Password:')
             ->addRule(Form::FILLED, 'Prosím zadajte heslo.');

        $form->addSubmit('send', 'Log in!');
        $form->onSubmit[] = array($this, 'loginFormSubmitted');
        $form->addProtection('Prosím odošlite prihlasovacie údaje znova (vypršala platnosť tzv. bezpečnostného tokenu).');
    }


    public function loginFormSubmitted($form)
    {
        try {
            $user = Environment::getUser();
            $user->authenticate($form['login']->value, $form['password']->value);
            $this->getApplication()->restoreRequest($this->backlink);
            $this->flashmessage('fsdfsdfsdf', 'jj'); // nejde
            $this->redirect('Dashboard:default');

        } catch (AuthenticationException $e) {
            $form->addError($e->getMessage());
        }
    }

}
?>

Poradte pls, kde by som mal debugovat (Xdebug mi ako tak ide). Napr. pri logoute mam v URL identifikator _fid, ale message nikde. Este sem dam kus layout, ale ten mam tiez zo skeletonu:

<div id="content">
  {foreach $flashes as $flash}<div class="flash {$flash->type}">{$flash->message}</div>{/foreach}
  {include #content}
</div><!-- #content -->
