I think you can access any controller method from within view or
layout:
$this->controller->flash('');
BUT I'm not sure.
Flash method is not intended to be used inside view for it has it's
own view and layout app/views/layouts/flash.thtml
Try using $session->flash($key) inside your views. It does not
redirect, however.
