is that your controller code ? seems pretty explicit, which is fine
because thats what you needed there. but im looking for just your
basic "add"/"edit" methods, that just load some objects, change them
around, and its done. would rather not have *any* explicit step that
has to be repeated in controller methods for a basic flush/commit
(other than a decorator). otherwise it basically means putting
"session.flush()" at the end of every controller right above the
"return" and id rather not have to do that...not just for appearance,
but also because abstracting away the transactional strategy it
leaves room for it to be tuned/modified at the library/
configurational level.
