After following the directions in ZF-9148, cache files are being created, but are empty.

I have the following lines in my application.ini file:

; Custom Caches (Adjustments To Default CacheManager)
resources.cacheManager.page.backend.options.public_dir = APPLICATION_PATH "/../public/cached"
resources.cacheManager.pagetag.backend.options.cache_dir = APPLICATION_PATH "/../data/cache/tags"

The following is my controller:

class TestController extends Zend_Controller_Action
{
  public function init()
  {
            $this->_helper->cache(array('index'), array('testentry'));

  }

  public function indexAction()
  {
    $this->view->testinfo = "Testing";
  }
}

However, the files produced contain no data whatsoever. It appears that library/Zend/Controller/Dispatcher/Standard.php issues an ob_get_clean() command prior to the View actually being rendered.
