zend-framework2 - ZF2: unable to fetch or create an instance for partial

Question

I am trying to use partials in my layout on ZF2.

I tried few methods (including those that are described here, where a user has to include a partial to the rout in the module config). Every time I am getting the same error.

For example, I am following instructions from the ZF2 documentation: http://framework.zend.com/manual/2.2/en/modules/zend.view.helpers.partial.html#zend-view-helpers-initial-partial

partials.phtml is in the same folder as the layout.phtml. The server (and I tried both, apache and building PHP server) throws an error:

[Fri Jun 14 18:40:34 2013] 127.0.0.1:36616 [500]: / - Uncaught exception 'Zend\ServiceManager\Exception\ServiceNotFoundException' with message 
'Zend\View\HelperPluginManager::get was unable to fetch or create an instance for partial' in /var/www/frameworks/ZF2/library/Zend/ServiceManager/ServiceManager.php:496

#5 /var/www/frameworks/ZF2/library/Zend/View/Renderer/PhpRenderer. in /var/www/frameworks/ZF2/library/Zend/ServiceManager/ServiceManager.php on line 496

I am using PHP5.5.0RC3, ZF2.2.1 and Apache 2.2.15

Any suggestions would be appreciated.
