Reinhard,

thanks for the reply. But as I understood it, for a single script there may
be multiple continuations at any point in time, all corresponding to
different page submissions so that if you use the browser back button,
submitting that page can use that particular continuation to restore the
intepreter state as it was when that page was being submitted the first
time. That's even the example given in the documentation? So I don't
understand your point, I'm sorry. Can you clarify further on this? Thanks!

Regards,
Francis

This is the intended behaviour because it would cause high memory
consumption if you connect the complete state of your application with a
continuation --> acontinuation "only" represents a certain point at your
flowscript where the script can be continued.
