Ricardo Tercero Lozano commented on MYFACES-3835:
-------------------------------------------------

The wicket issue describes what´s really going on. This problema affects only 
to Chrome (not IE nor FF) just for the CDATA sections split and the myfaces JS 
taking only the first section.

I think its really a Chrome (or libxml2) error, but we have to live with it, 
and I really appreciate any help you could provide to workaround this problem.

Thanks.

> On certain conditions viewstate gets corrupted (truncated).
> I've got a page with a richfaces fileupload component. The page works well on 
> IE7 and Firefox (latest), but not in chrome. Digging into Javascript and Ajax 
> response I got some extra info about the problem. I don't know why, but a 
> partial response like:
> <?xml version="1.0" encoding="utf-8"?><partial-response><changes><update 
> id="javax.faces.ViewState"><![CDATA[....
> results in two CDATA sections when handling the response. This is the problem 
> caused by Google Chrome. Inspecting the JSF.JS library, the line that gets de 
> updated view state is:
> mfInternal.appliedViewState = node.firstChild.nodeValue;
> This line is in 'processUpdate' method. When Chrome, for some reason splits 
> the original CDATA block into two, that line only updates the first section, 
> obtaining a truncated viewState and ViewExpiredException in next request.
> The first CDATA section created by Google Chrome has 300 bytes. Weird, but 
> searching Google for 'Chrome cdata 300' appears to be a libxml2 problem.
