I believe your issue is with the lack of a setParameter(String name, String value) method in Java's ServletRequest Class (and by extension HttpServletRequest sub interface). If you wish to change a user's request by appending, deleting or changing information, you must read the the parameter map into an attribute map (or additional map of your choosing) and then only use the information from the attribute map for any "work" that needs to be done. Otherwise, you must setup the request paramter map by changing the request in each ftl (or screen definition, etc).
