repeat number of event listeners?
In as3, if I add identical event listeners to an object, for examle

    txtField.addEventlistener( Event.CHANGE, changeCb, false, 0, true );
    txtField.addEventlistener( Event.CHANGE, changeCb, false, 0, true );

would I need to remove that listener twice?

How can I get a list or the number of event listeners on an object?
