Subject svn commit: r920500 - in /myfaces/trinidad/branches/jsf2_ajax/trinidad-impl/src/main/javascript/META-INF/adf/jsLibs: Page.js xhr/RequestQueue.js xhr/XMLRequest.js xhr/XMLRequestEvent.js
Date Mon, 08 Mar 2010 20:38:19 GMT
Author: arobinson74
Date: Mon Mar  8 20:38:18 2010
New Revision: 920500

URL: http://svn.apache.org/viewvc?rev=920500&view=rev
Log:
Move the JSF2 AJAX 'switch' code to the request queue and undo the hacks placed in Page.js.
Added a switch that we can use to eventually select if JSF2 AJAX is used or not on the client
