[fw-mvc] Layout->action() and caching before dispatch

Hello,

i use the Zend_Layout and have some placeholder areas.

I fill thouse placeholders with this code:

$view->placeholder('Login')->set( $view->action('simple','Login'));

The most of this Holders are cacheable and i've develop a
Helper_Action and i'll found a better solution.

Thanks a lot

Marcel
