For some reason this doesn’t work on IE if I do not return a value. It works perfectly on Firefox though. Here’s my code:
[code]
window.onbeforeunload = callFlex;
function callFlex(){
MyAppication.myFlexFunction();
}
[/code]

What a great and simple solution, it was exactly what we were hoping for. Thanks for sharing!

Hello Evan! Happy New Year! I don’t have a mac (yet) so I didn’t tested it on mac. You may be right. The event may be triggered only on win platform. Regarding the win platform I am sure that is working only on FF and IE. You can try using the onunload (not onbeforeunload) event of IE browser (if you can install it on mac).

This event doesn’t seem to be fired on the mac platform, for firefox or safari. I’ve been trying desperately to find a hook to clean-up the app on exit. I suppose Adobe figured that removing the application is sufficient, but it’s not when the app connects to a stateful back end.

the onbeforeunload event used in the javascript above is fired not only when the browser window is closed but also when the page is refreshed (annoying!). I couldnt find a good solution on the web which distinguished a browser close from a refresh event.

This, however, does not address navigation from within the Flex app. Any mechanism to perform similar “gate keeping” function prior to removeChild() is executed and, for example, the view stack is swapped.
