Zend_Navigation and module specific layout

Question

I am developing a web site using the Zend Framework. I was using this site to get my navigation working: http://www.rvdavid.net/zend_navigation-makes-writing-navigation-for-zf-sites-very-easy/.

However, the $this->layout()->menu returns NULL. I have a modular structure, with a plugin that takes care of module specific layout:

<?php
class Custom_Controller_Plugin_ModuleBasedLayout 
    extends Zend_Layout_Controller_Plugin_Layout
{
public function preDispatch(Zend_Controller_Request_Abstract $request)
{
        $this->getLayout()->setLayoutPath(Zend_Registry::get('config')->resources->frontController->moduleDirectory
        . DS . $request->getModuleName() . DS . 'layouts' );
}
} 

Does anybody have a clue why my navigation isn't working?

Answer 1

its $this->navigation()->menu();

not $this->layout()->menu

all the rendering stuff of Zend_Navigation is done by navigation view helper which you use in *.phtml files
