Justin Mclean resolved FLEX-14394.
----------------------------------
Resolution: Not A Problem
sample code contained infinite loop
> Error: Error #1023: Stack overflow occurs on dispatchEvent
> ----------------------------------------------------------
>
> Key: FLEX-14394
> URL: https://issues.apache.org/jira/browse/FLEX-14394
> Project: Apache Flex
> Issue Type: Bug
> Components: Events
> Affects Versions: Adobe Flex SDK 3.0 (Release)
> Environment: Affected OS(s): Windows
> Affected OS(s): Windows XP
> Browser: Firefox 2.x
> Language Found: English
> Reporter: Adobe JIRA
>
> My real problem application uses 7 components in the view stack and if
> you need it, I can make it downloadable from my server. It is about 50 meg,
> but some of that is video. I am attempting to design an OO style approach to
> shutting off a video player when the View Stack is switched away from the
> View that has the player component. I can do this in another design pattern
> that is tightly coupled, but I want the behavior to be transfered via event
> bubbling. My component will listen for the IndexChangedEvent.CHANGE, test
> it and start or stop the video.
> The issue is that when I select to change the View Stack, it goes into an
> endless loop from the handler method until it blows with a stack trace.
> Compile and run the example code below...
