[Magicajax-cvs] magicajax/Core/script AjaxCallObject.js,1.1,1.2

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Update of /cvsroot/magicajax/magicajax/Core/script
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv20348/magicajax/Core/script

Modified Files:
	AjaxCallObject.js 
Log Message:
Firefox keeps the form data of a page when doing a page reload or using 
the back/forward button.
However, the 'RenderedByScriptControls' will disappear after a reload. 
To redraw these controls on the page, we will force a callback from the client's
window.onload when the value of hidden field '__RBSCONTROLSEXIST' 
equals '1'. This hidden field is set to '1' whenever a callback is made.
On first page rendering, the value of this hidden field is '0'.
Internet Explorer always resets all form data on a page refresh (also the hidden 
field '__RBSCONTROLSEXIST'), so for IE no extra callback will be forced.
