Hi,
I got error when rendering response after a ajax request in IE9.
After some investigation, this issue do not exist if you use compatible mode.
However, the same error can be found in the demo page
http://richfaces-showcase.appspot.com/richfaces/component-sample.jsf?demo=log&skin=blueSky
The Richfaces script return "error@malformedXML" during processing the response.
I have found a discussion for fixing RF 3.3.X for IE9 but not RF 4.x.x.
Is there any plan for the fix into RF4
