[fw-mvc] Reusing controller instances

I have a simple controller set up that contains two actions. When I call $this->action from within a view script on the other action in the same controller, it seems that a new instance of the controller is created instead of reusing it. This means that my init() method is being called twice. Is there a way to prevent the dispatcher from creating new instances of the same controller during the same request? Can it be made to re-use an existing controller object and only call preDispatch(), action, postDispatch()?

Here's some simple test code showing init() being called twice.

<?php

class MyTestController extends Zend_Controller_Action

{

    public function init()

    {

        parent::init();

        echo 'MyTest controller initialized<br />';

    }

    public function preDispatch()

    {

        // disable view script rendering for all actions

        $this->_helper->viewRenderer->setNoRender(true);

        // disable layout for testing

        $this->_helper->layout->disableLayout(true);

    }

    public function indexAction()

    {

        echo 'index action called<br />';

        // also render search action

        echo $this->view->action('search', 'my-test', 'default', array());

    }

    public function searchAction()

    {

        echo 'search action called<br />';

    }

}

Output:
MyTest controller initialized
index action called
MyTest controller initialized
search action called
