[fw-general] init on extended objects

[Gunter Sammet]

Having some issues with inheritance and calling the init function. My
controller classes inhert from:

AdminController extends SaSo_Controller_Action

and

SaSo_Controller_Action extends Zend_Controller_Action

I added the constructor in both classes (AdminController and
SaSo_Controller_Action):

    public function __construct(Zend_Controller_Request_Abstract $request,
Zend_Controller_Response_Abstract $response, array $invokeArgs = array())
    {
        parent::__construct($request, $response, $invokeArgs);
        $this->init();
    }

I assumed that init() in each class gets called. However, this haven't been
the case. So I tried to call the parent init function:

AdminController:
    public function init()
    {
        parent::init();
        $this->view = SaSo_Registry::get( 'view' );
        $view->leftNavigation = 'admin';
        $view->leftNavigationCap = ucfirst($view->leftNavigation);
        $view->bodyContentImage = 'hed_admin.gif';
    }

SaSo_Controller_Action:
    public function init()
    {
        parent::init();
    }

Here 2 questions:
   -It doesn't seem that the view variables have been assigned. What could
be the reason?
   -Would the init function be called twice if it's called in each
constructor and also in each init function?

Any insight would be appreciated!
TIA
