Re: [fw-mvc] ZEND MVC and AJAX

Are you using a layout? If so, you'll need to exit at the end of your action (to prevent the layout from being rendered). That's because $this->_helper->viewRenderer->setNoRender() only disables rendering of the action, not the layout. 

Or, better yet, use the ajaxContext action helper. It will automatically render the correct view script and disable the layout.
