Zend Framework switching views in action

I have an action in a controller that is supposed to display different types 开发者_运维问答of output depending on the value in a dropdown on a form.

I have written a Templater object (extends from Zend_View_Abstract) for the different view types.

I have tried running the following code:

public function generateDocumentAction()
{
    //...some code to set $view depending on post data        
    // e.g. $view = new TemplaterOdt(); //view as an OpenOffice document

    $this->_helpers->getHelper('viewRenderer')->setView($view);

    $this->view->myvar = $form->getValue('some_value');
}

but $this->view is still the default one (a Smarty templater) which which is set in /public/index.php

I've looked in the documentation to and it says you can set the view in the init() function in the controller http://framework.zend.com/manual/en/zend.view.scripts.html but this would set the view for the entire controller which I don't want.

How can I change the output type for just this action?

If you just want to change the template to be rendered, use:

$this->_helper->viewRenderer('viewscripthere');
