debugging Flex event flow

I'm stepping through my code to figure out why a certain function takes more time to run the first time it gets called than on successive ca开发者_运维技巧lls. The code flow for each function call is the same up to when a dispatchEvent gets called. I'm pretty sure it's different afterwards, as that call takes a lot more time the first time around. Unfortunately, I have no idea which other parts of the code chew on this specific event and thus cannot step through the handling of such event.

The question: is there a way to either figure out who handles such events or magically step through the handling code without explicitly setting breakpoints there?

thank you!

Not in an easy fashion, no. It's a pro and con of Flash (or any event based framework). You don't know when it's fired, where it's fired from (think bubbling), or who is listening for it. But at the same time, anyone could listen for any event, from anywhere (so long as it's within the display tree).

Normally what I do is just do a workspace search (ctrl+H in Flash Builder) and search for that specific event (you should be using static constants for dispatching/listening event types) and see who's doing what.
