I think I have found the solution to the issue 2). In t_tokens.xhtml page I've replaced : | <ga:responseActions> | <gd:sort source="#{token.availableTransitions}" target="#{transitions}" entryVar="e" argument="#{e.name}"/> | </ga:responseActions> | | for: | <ga:responseActions> | <gd:sort if="#{! empty token.availableTransitions}" source="#{token.availableTransitions}" target="#{transitions}" entryVar="e" argument="#{e.name == null ? '' : e.name}"/> | </ga:responseActions> | View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4214608#...
