If you have Controller, you're not using Struts - you're using Spring MVC. ;-)
If you look at the latest code for UserFormController.java in
Subversion, we've changed the formBackingObject method so it
re-fetches the user from the database before populating it with
request parameters. If you change your code to match, it should solve
this problem for you:
protected Object formBackingObject(HttpServletRequest request)
throws Exception {
if (!isFormSubmission(request)) {
String userId = request.getParameter("id");
// if user logged in with remember me, display a warning
that they can't change passwords
log.debug("checking for remember me login...");
AuthenticationTrustResolver resolver = new
AuthenticationTrustResolverImpl();
SecurityContext ctx = SecurityContextHolder.getContext();
if (ctx.getAuthentication() != null) {
Authentication auth = ctx.getAuthentication();
if (resolver.isRememberMe(auth)) {
request.getSession().setAttribute("cookieLogin", "true");
// add warning message
saveMessage(request,
getText("userProfile.cookieLogin", request.getLocale()));
}
}
User user;
if (userId == null && !isAdd(request)) {
user =
getUserManager().getUserByUsername(request.getRemoteUser());
} else if (!StringUtils.isBlank(userId) &&
!"".equals(request.getParameter("version"))) {
user = getUserManager().getUser(userId);
} else {
user = new User();
user.addRole(new Role(Constants.USER_ROLE));
}
user.setConfirmPassword(user.getPassword());
return user;
} else if (request.getParameter("id") != null &&
!"".equals(request.getParameter("id"))
&& request.getParameter("cancel") == null) {
// populate user object from database, so all fields don't
need to be hidden fields in form
return getUserManager().getUser(request.getParameter("id"));
}
return super.formBackingObject(request);
}

I think I must be missing something. I only have xdoclet tags in my User.java
and Person.java
My UserController and UserFormController don't have any tags - are those the
files you were referrign to?
They do use the request to get information. Should I change that to session?
