I have read the wiki tutorial and previous v1.3 anouncment posts in the forum and I understand the concept of notifieriers, but cannot get it working...

I presumed, that when I save a new class which has
Code:
$_SESSION['cart']->attach($this, array('NOTIFIER_CART_ADD_CART_END', 'NOTIFIER_CART_REMOVE_END'));
or similar in the class consturctor, then the observer class should implement the code and wake it up, when notified, but nothing... [Tried also with the original code in the wiki]

As far as I understand, the application_top does not read in the classes that are saved under includes/classes/observers catalog, so the class and its constructor that should attach notifier to praticular event is never called and observers array stays empty... Should aplication_top read in all observers that are saved into this folder or should I explicitly say somewhere, that these classes should be included, so the class constructors are waked and observers are added to observers array?

Debuging the code with breakpoint at class.base notify function indicates indeed that $this->observers array is empty in spite of the fact that I copied the observer code from the wiki API...
