Why didnt I use html:hidden? Whenever I use that I have parsing error and exception thrown which I think is because of the <bean:write> within <html:hidden>. Using <input> didn't cause any problem.
If html:hidden will not cause the problem and I am doing it the wrong way. Pls advise. Ok..now I understand the scope implication. I guess the only way to resolve this is to put everyting into session instead of request.
