Hello RichFaces Team/Supporter.
what can I do to call an event from panelBarItem or an alternative.
Is this feature plant in a later release?
Currently panelBar is a "client" component. It doesn't submit anything, so actions cannot be triggered. You can file the request for that feature to JIRA in order to queue it for the future versions.
Have you tried to use a4j:suport with this component ??
I´m not sure if it works, but..
