A form does not have an action associated with it. Only command 
components (commandButton, commandLink) can execute actions.

However the command component can be invisible (style="display:none"), 
and be triggered from javascript.

The necessary script can be written manually (see the myfaces wiki) but 
the sandbox s:submitOnEvent tag makes this easier:
