Description

Steps to reproduce:
1. add and eventlistener for the add and remove events on a component
2. add the component to the container

Actual Results:

Listener is not called

Expected Results:

Listener gets called

Workaround (if any):

The problem appears to be in Container.as. The following line was added in 4.0:

if (hasEventListener(FlexEvent.ADD)) /** new line **/
child.dispatchEvent(new FlexEvent(FlexEvent.ADD));

before calling dispatch. Thus, the parent must have the "ADD" listener for it to work. This is incorrect. The child should be checked for the listener not "this".
