Custome events and Listener methods

Hi I've written a collection class that extends arraylist, a custom event the extends eventobject and a custom listener.

I have the customlist.add() trigger a listener method and the customlist.addAll(collection) trigger another listener method.
Both methods work, however, when I run customList.addAll(collection) both listener methods get triggered. the listener method that is triggered with customList.add() gets triggered as many times as there is elements in the collection being added.

Is there a way to stop the listener method triggered by customList.Add() from tirggering when I add a collection to the customlist without writing a second listener?
Is there a way to detect if an object is part of a collection?
