Child1 dispatches the event, the event bubbles up, Container handles it, but sees that actual event hanlder is in child2 and lets chuld2 handle it. So, where to remove the listener? If I have child2.removeEventListener("remoteDateEvent", remoteClickHandler); outide of child2 then I am getting an error message: 1120: Access of undefined property remoteClickHandler --- In [email protected]<mailto:flexcoders%40yahoogroups.com>, "Paul Andrews" <p...@...> wrote: > > According to your original explanation the only event handler for > "remoteDateEvent" is added to the parent container.
