Zend Framework: My form wont render - zend-framework

Question

So I have created a form below with Zend Framework which I'm then going to customise. My first issue is that with the csrf hash security I get an application error. However, when I remove them lines all I get is a blanks screen which is only resolved when I remove the CPATCHA protection. Can anyone explain to me why?
My Form:
class Application_Form_Clips extends Zend_Form
{
public function init()
{
// Set the method for the display form to POST
$this->setMethod('post');
// Add an email element
$this->addElement('text', 'email', array(
'label' => 'Your email address:',
'required' => true,
'filters' => array('StringTrim'),
'validators' => array(
'EmailAddress',
)
));
// Add the comment element
$this->addElement('textarea', 'comment', array(
'label' => 'Please Comment:',
'required' => true,
'validators' => array(
array('validator' => 'StringLength', 'options' => array(0, 20))
)
));
// Add a captcha
$this->addElement('captcha', 'captcha', array(
'label' => 'Please enter the 5 letters displayed below:',
'required' => true,
'captcha' => array(
'captcha' => 'Figlet',
'wordLen' => 5,
'timeout' => 300
)
));
// Add the submit button
$this->addElement('submit', 'submit', array(
'ignore' => true,
'label' => 'Sign Guestbook',
));
// And finally add some CSRF protection
$this->addElement('hash', 'csrf', array(
'ignore' => true,
));
}
}
My Controller:
class AdminController extends Zend_Controller_Action
{
public function init()
{
// get doctrine and the entity manager
$this->doctrine = Zend_Registry::get('doctrine');
$this->entityManager = $this->doctrine->getEntityManager();
// get the users repository
$this->indexVideos = $this->entityManager->getRepository('\ZC\Entity\Videos');
$this->indexClips = $this->entityManager->getRepository('\ZC\Entity\Clips');
}
public function indexAction()
{
// action body
}
public function clipsAction()
{
// get a form
$form = new Application_Form_Clips();
$this->view->form = $form;
}
public function videosAction()
{
// action body
}
}
My View:
<?php echo $this->form; ?>
