Intellij Idea - pathetic debugging for Flex

Almost two months ago, my company switched to IntelliJ Idea from Flex Builder

for Flex development. I am very sorry to say that it sucks, when it comes to debugging.

Its stack trace for breakpoints is WRONG in 99% cases which makes

it very difficult to debug reliably.

Printing stack trace in Flex

trace(new Error().getStackTrace());

IntelliJ Idea - Conditional breakpoints for flex

Update to New version of Intellij Idea
if you haven't already.

it contains few new features :

including conditional breakpoints for flex.

Developing for Flash with Flex?

Breakpoints can trigger Firefox's hang protection. You can disable hang protection by setting dom.ipc.plugins.timeoutSecs to -1. 

See Disable Hang Protection for details. 

in a firefox tab, type about:config

and set

dom.ipc.plugins.timeoutSecs to -1.
