There is an implementation for this in old FOM (or anything this is named).
This has never been transferred to new FOM as this practise is considered
not elegant. I am also not happy about it as I like to prototype web
applications using XSP actions which helps a lot. 

Still I do not understand why an xsp action is a bad thing. As long as you
code only application logic there (and no redirects) it is a nice separation
from controller itself (flow) and does not involve much coding.
