Please don't write things like "is this a bug" in all caps. It is not a bug in this case, and I have never once in 5 years of involvement in user forums like hibernate.org or jboss.com, seen a single case where a user who claimed to have found a bug in all caps had actually found a bug. The h:commandButton control does not support f:param in JSF, so you should use s:button instead. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4016155#...
