I agree completely. Custom messages are for the intermediate programmer, at least. I wouldn't recommend them for a beginner. On the other hand, I don't think you can consider yourself an advanced coder unless you understand custom messages (including when to use them). > Sounds like you missed Event.COMPLETE, it is just as good to signal when a > task is done. No, I know all about Event.COMPLETE. I have a lot of things happening that send a message when they finish, and I like to target the right method. Another legimate approach would be to send all the Event.COMPLETE message to a method that decides where to route them, probably in a switch statement. I just happen to prefer to target a specific listener. > Did you bother adding any properties in your custom class? If not, you could > just have used the Event class instead. Of course. The custom class has properties and methods that aren't in the Event class. > Actionscript is a garbage collected language, objects can not vanish while > they are used as the value of this for a method.

My blunders now are more sophisticated ;-) I think it's a valid point, though--even though it's garbage-collected, it still has a call stack. If a method in object A calls a method in object B, object A won't be eligible for garbage collection until the method in object B is finished. An advanced programmer will understand this (or at least should). It could lead to hard-to-find bugs, though. If you destroy an object while it's on the call stack, you will get, at a minimum, a memory leak. Things like a call stack, garbage collection, memory leaks, and the like are more advanced concepts. And, as Jason says, we should be willing to accomodate less-advanced coders here.
