Ben Gunter resolved STS-866.
----------------------------
Resolution: Won't Fix
Stripes simply cannot determine the event in a situation like this. Every time
an internal forward is executed, it carries forward all the parameters from all
the other requests (external or internal) that have already executed. That is
exactly what is happening in this case: all your event parameters are carrying
forward, and Stripes has no idea which one to use in the end. The special case
of ForwardResolution(Class, String) handles these kinds of conflicts
internally, but there's nothing that can be done when you're just using
parameters to specify the event.
> The ForwardResolution don't clean the previous event causing the error
> net.sourceforge.stripes.exception.StripesRuntimeException: Multiple event
> parameters [jsp, forward, init] are present in this request. Only one event
> parameter may be specified per req
