Lukáš Fryč commented on RF-13115:
---------------------------------

Did a little bit more search, seems you could use onbeforeunload.
https://developer.mozilla.org/en-US/docs/Web/API/window.onbeforeunload#Browser_compatibility

At least you can cancel the unload and do your job.

> Requirement : I need to call a method on backing bean on event of page unload. Approach : So i have created a a4j:jsFunction and am trying to call it on window.unload event. 
> Issue Description : When the page refreshes, js function attached to window.unload event is called and executes correctly. All statements in console.log() are called correctly. But, the method in the backing bean is never called.
