Calling getMemberNames on an EventDispatcher returns null, even the the "instanceNames" parameter set to true. Attempting to access the private "listeners" property of an EventDispatcher, which shows up in the debugger, generates a runtime error, which is the standard behavior in ActionScript 3. Obviously, none of the previous posters have actually tried this, nor has the poster of the code. That code does not work.

Very interesting indeed :) In some memory leak hunting scenarios I've found useful monkeypatching FlexSprite and overriding addEventListener to keep a list of listeners as described in dough McCune's post: http://dougmccune.com/blog/2008/02/21/monkey-patching-flexsprite-to-list-all-event-listeners-on-any-flex-component/ It's the hackish way to accomplish the same... I'll definitely give it a try when I have some time. Thanx for sharing! cheers Never checked the profiling APIs before.
