如何在flex / actionscript 3中找到在哪里创建对象？

Question

In my project I have noticed 20-40% CPU time when my app is idle.
In debugger when I pause I always land on a flex.utils.Timer/tick.
This timer has 30ms delay between "ticks"

I didn't create that Timer... so this is problably a component I have added

Unfortunately it will be difficult to remove all compenents until if find the "one" ..
Yes I should have notice the CPU usage sooner !
and yes I will do that if I don't find another solution

I am of course using some components without having their sources...

My questions :
* How can I find the guilty component ?
* I tried to find it using Kap Inspector without success ...any tips for Kap inspector ?
* Is there another great tool to track object creation ?

Thanks for your help

No idea about Flex, but for your CPU problems, check this out:

Answer 2

When you set your breakpoint, in the Flex Debugger perspective, find the Variables tab/view. From there, with your breakpoint set, you should be able to see all of the variables currently in local scope (local to the timer-tick event handler, that is). The event variable will contain information about the timer itself -- eg, in event.target -- and the this variable will tell you where the timer handler is defined.

From there, you might be able to walk back up the stack trace, using the Debug tab/view (with your breakpoint still set), to get a sense of where the Timer object might've been instantiated. If that doesn't work, you can download a trial of Flex Builder Professional here:

... and give the built-in profiler a try. Hope that helps point you in a helpful direction!
