1/ you currently cannot add triggering ports in the deployment, you
    have to add them to the task context definition. I actually think
    that doing it at deployment time would be a lot nicer, I'll have to
    have a look at whether it is possible
2/ the documentation is in error. periodic activities override the
    other behaviours. What you can have is an fd-driven task that is
    also port driven, though. I just pushed a fixed version of the
    documentation (should be up-to-date tomorrow)
