EJB/JSF Clearing a form upon returning to it

[tom.simmons]

Hi

My application is working fine, I am just on the polishing stage now.

I have various search screens in the system and what currently happens
is if you use one of these, then navigate to a different area of the
system, when you return the last search parameters and results are
still displayed.

Now because the navigation is not done through the backing bean there
is no where to clear the details out when you depart. Similarly, when
you return, because I can't think of a way of knowing where you came
from you can simply clear the form then, because you might be
redisplaying as part of building the search parameters.

Any ideas?

What's the managed-bean-scope of that bean? If it's "request" it should clear
any time you arrive from a different screen.

Sadly this is not an option, the screens all have cascaded list boxes
on them. If the scope were request it is new for each time its
entered and therefore the cascades would not work.

The only idea I have so far is to examine the request and see if there
is anyway of knowing where it came from, or in the naviagtion rule see
if I can add a parameter on the destination.
