Can you give an example of the memory leak you are talking about and
also an example of the arguments.caller remove listener? I have not
heard of this before.
Is the memory leak issue caused when you nest a function inside a class?
class myClass {
function myClass() {
obj.addEventListener("onWhatever", Delegate.create(this,
myCustomMethod));
// nested function not member of class - this causes memory leak???
function myCustomMethod(evtObj:Object):Void
{
// code
}
}
}

what john is outlining here is fine in essence, but unless you never want to
remove this event listener this will cause a memory leak. either you create
the delegate function on a class scope or you use arguments.caller in the
handler function to remove the event listener

.... and if you want to point that dispatched to a custom method not named
the same as the event:
obj.addEventListener("onWhatever", Delegate.create(this, myCustomMethod));
private function myCustomMethod(evtObj:Object):Void
{
// code
}
Also, you don't need to include "target" in your dispatch, EventDispatcher
includes that for you.

Just make sure int he constructor you initialize it::
EventDispatcher.initialize(this)..
also you ned to have these var definititions:
public var addEventListener:Function
public var removeEventListener:Function;
private var dispatchEvent:Function
then to dispatch:
dispatchEvent( { type:'whatever', target:this,
someOtherProp:'somothervalue' } )
all those props in the dispatchEvent call are just properties in a
basic Object. you must have type though.

This may be a "duh" question, but when you use dispatchEvent in a
custom
created component, can I use my own event name or do i have to use
one of
the built in ones of an object. For example, I am creating custom
quiz
component (the built in ones dont have the flexibility we need) and
would
like to add a 'QuestionCompleted' event. Is this possible?
