Description (*)

Fixed a documentation block typo on Mage::addObserver.

From "Add observer to even object"

/**
 * Add observer to even object
 *
 * @param string $eventName
 * @param callback $callback
 * @param array $data
 * @param string $observerName
 * @param string $observerClass
 * @return Varien_Event_Collection
 */
 public static function addObserver($eventName, $callback, $data = [], $observerName = '', $observerClass = '')
 { }

---

To: "Add observer to events object"

/**
 * Add observer to events object
 *
 * @param string $eventName
 * @param callback $callback
 * @param array $data
 * @param string $observerName
 * @param string $observerClass
 * @return Varien_Event_Collection
 */
 public static function addObserver($eventName, $callback, $data = [], $observerName = '', $observerClass = '')
 { }

1. Open app/Mage.php and locate the static function addObserver -- Mage::addObserver

@ADDISON74 is the wording ok? :-)

Is it a trick question? At first glance I can't find anything wrong.

hahaha no it's not a trick question :-D

"Add observer to events object" maybe should be "Add observer to event objects"?

[fballiano]

no, my fault, it calls "getEvents()->addObserver" so @denisahac is totally right, sorry about that
