Upon futher investigation, this appears to be related to using ajax4jsf. I can revert back to a version without ajax4jsf that works, and then after integrating ajax4jsf the problem previously outlined occurs. I thought this may be caused by the view handler that ajax4jsf uses, but it use the standard facelets view handler (see below). Anyway, if anyone has any thoughts let me know, Cheers, Pete. web.xml | <context-param> | <param-name>org.ajax4jsf.VIEW_HANDLERS</param-name> | <param-value>com.sun.facelets.FaceletViewHandler</param-value> | </context-param> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3985793#...
