You're replacing your _triggers NSMutableArray with an NSArray on init. :-)

[NSMutableArray array] returns an NSArray - immutable.

That is incorrect; -[NSMutableArray array] returns an autoreleased NSMutableArray. Notice that it returns an object of type "id" rather than an object of type "NSArray"... That's so subclasses can return their own version of the object.
