Hold on. You have to have all necessary information, when you are generating
the link. It does not matter, whether the keys in the map are hardcoded or
determined during the runtime. Important is that you are creating the link
on the server side, before the user clicks on any checkboxes.
If you want to use user's input, you can do it when serving the next page.
You can then generate the map in an Action and generate the link for the
next displayed page (so you will know all paramaters in advance, since
the checkboxes have been submitted already)
Or your Action can use the checkboxes to determine what to do or to
determine where to forward to. You don't need to use constant strings
in findForward.
Another possibility would be using JavaScript on the client, but since
many browsers have JavaScript disabled, you should not rely on it.
