When in layout we add several navigation rendering get fatal error:

echo $this->navigation('navigation');
$helper = $this->navigation()->findHelper('menu');
$helper->setContainer('secondnavigation'); // <- Fatal error: Call to a member function get() on a non-object in /usr/share/zf2/library/Zend/View/Helper/Navigation/AbstractHelper.php on line 222

echo $this->navigation('secondnavigation'); // <- render old 'navigation'.

for testing enough one navigation as this line also do error:

    $helper->setContainer('navigation');
