The root cause of this issue is a JSF spec problem which will be 
addressed as it seems with jsf 2.2.

The other workaround is to add all forms of the page as render targets
this is the official jsf 2.1 workaround.

The problem is you cannot enable a update all forms per page method per 
default because the javascript does not have any viewroot information
and updating all forms automatically would break the portlet environments.
