The problem here is that FormHelper does not load SessionHelper.
Sub-helpers do not merge automatically (unlike controllers), you have
to do it manually... like so
class AppHelper extends Helper {
var $helpers = array('Session');
function __construct() {
if (is_subclass_of($this, 'AppHelper')) {
$parentVars = get_class_vars('AppHelper');
$this->helpers = array_merge($parenttVars['helpers'], $this-
>helpers);
}
parent::__construct();
}
}
Please note: this is a very simplified example. It won't handle
plugins properly, or helpers with configuration arrays. But I'm sure
you get the gist.
