I am not sure whats good for you because I usually put the logic for same
"page" in the same Action. So for your case I would just write one Action.
However I do understand the need of separating modification logic from pure
display data logic.
In your case you could at one param in redirectAction for each parameter you
have so your Institution will get populated, but of course these parameters
will be transferred via Get parameters and shown on the browser URL.
or you could put them in session and take the values out when you get to
Institution.
These are the 2 ways i can think of write now.
dont know if anyone else can suggest better way of doing these
