Prevent Browser refresh on F5

Question

I've been ased to look at a Captivate problem.
The published Captivate movie is a swf embedded using SWFObject (1.5 I think)
When F5 (or other function keys) are used as shortcuts in Captivate simulations, when the user presses F5 the keypress gets bubbled up to the Browser window, and the page refreshes. I need to prevent this behaviour.
I've tested out a version of the code found here:-
http://www.gklein.org/tests/js/disablekey.html
in my browser window, and it works fine while the browser window has focus, but fails to catch/prevent refresh when I press F5 when the Captivate swf has focus.
So it looks like I need a way to prevent Flash from dispatching the F5 keypress out to the browser. How can I do this? Or is there a better way?

There is no easy answer for this. BEA portal is a stateful framework and HTTP wasn't meant to be. My recommendation would be get rid of the nested controller's and state wherever you can (session or pageflow variables) and actions that depend on state(e.g. previousAction currentAction etc). Your state should be part of the URL (i.e. normal REST principles)
This is difficult if you've already implemented code.
So if you only have these problems at specific places you might consider the redirect after post techniques (in your case The
c. third controller's "back"-action is executed, which forwards to the second controller's "returnAction"-action, rendering a new page would become
c. third controller's "back"-action is executed, which forwards to the second controller's "returnAction"-action going to a temporary page which then redirects to a new page. Any refresh now is not on the "back" action but on the new page redirect. This also prevents the user using the back button (but not if he hits it twice quickly :) )
