Sateesh Jaladi commented on FLEX-33662:
---------------------------------------

Accepted, but it should allow to remove the event listeners, let's say wrapper in case of second example.  If we are unable to remove, the object won't be garbage collected, lets say we are having some 100 mxml files in a application that uses event listeners same as explained in second example (without specifying event object as parameter), that means those 100 objects won't be garbage collected? I don't think its a good solution either.

> Events added as part of mxml can not be removed.  Even some of the events come default without creating them.  Add a list component and create handler for "applicationComplete" event in application tag and check if the list component is having event listener for "change", (using hasEventListener(Event.CHANGE)) it will exist even though I haven't added one.  Apart from this, If I add "changing" in List mxml like <s:List id="list" changing="changingHandler()" />, I cannot remove the listener for "changing" event, even if I  try to remove and test to see the same by using "hasEventListener('changing')" with the list component, its returning "true" only and never "false".  The generated actionscript gives a hint like its creating own listeners and if we use the same listener to remove in application we see the output for "hasEventListener('changing')" is false.
