Hmm, looks a bit dirty having a genres.html file producing JSON.

In FLOW3 I'm using the concept of formats: the request object contains  
the currently
requested format (html, json, xml, ...) and the action controller will  
automatically
select the right Fluid template or view. The big advantage is that you  
don't need to modify
the controller at all for providing a JSON view.

Some untested sample code (note the small name changes):

class Tx_MvcExtjsSamples_Controller_GenreController {

    public function indexAction() {
       $genreRepository =  
t3lib_div 
::makeInstance('Tx_MvcExtjsSamples_Domain_Repository_GenreRepository');
       $genres = $genreRepository->findAll();
       $this->view->assign('genres', $genres);
    }

}

index.html:
    <ul>
    <f:for each="{genres}" as "genre">
       <li>{genre.title}</li>
    </f:for>
    <ul>

index.json:
{namespace mvcextjs=Tx_MvcExtjsSamples_ViewHelpers}
<mvcextjs:json>{genres}</mvcextjs:json>

Cheers,
