The tutorial uses cycle.setPage to switch pages in a listener, so that's what I normally do.
During a request cycle, you need to throw RedirectExceptions to move to a different page - cycle.setPage in beginResponse, for instance, has no effect.
I think you should be able to use the same technique in either situation - set up a page, call a method to move to that page (IMO you shouldn't need to throw an exception in either case). How about a redirect method in IPage? Then it's always obvious how to switch pages. Behind the scenes, I suppose redirect could always throw a PageRedirectException.
Does anyone else have an opinion on/care about this? I only mention it because I have fumbled around more than once before remembering about PageRedirectException.
