It depends on what you want to do then - if you want to clear the 
EventQueue and simply pass the event flow to the login-event, you can 
use InterruptDispatchException. However, what we did in this case was to 
persist the initial request (which is IMHO somehow supported by 
barracuda itself, but I don't remember that in detail right now) and the 
throw a ClientSideRedirectException (CSRE) to the loginscreen. When the 
use is actually logged in, we throw a CSRE again to get into the 
originating event flow.
