    Is it possible to print a list of active event listeners/be sure that one has been removed?

    Hi, I was wondering if it's possible to retrieve a list of all the eventlisteners running for debugging purpose.

    I was thinking to something like this, but reading "eventListeners_table" if that exists.. :)
    			for key, value in pairs(_G)do
				print(key.."="..tostring(value))	
			end
    edit: either checking if "customEventListener" is still active could be of help... :-?

    Thank you

    P.

      @pie for debugging you could override EventDispatcher class, to store event listeners in internal table and then you could print that table as:
      EventDispatcher._addEventListener = EventDispatcher.addEventListener
 
function EventDispatcher:addEventListener(name, callback, data)
    if not self.__events then
        self.__events = {}
    end
    if not self.__events[name] then
        self.__events[name] = {}
    end
    self.__events[name][callback] = data
    self:_addEventListener(name, callback, data)
end
 
EventDispatcher._removeEventListener = EventDispatcher.removeEventListener
 
function EventDispatcher:removeEventListener(name, callback, data)
    if not self.__events then
        self.__events = {}
    end
    if not self.__events[name] then
        self.__events[name] = {}
    end
    self.__events[name][callback] = nil
    self:_removeEventListener(name, callback, data)
end
      ;)
