I just want test some new feature of 3.2.0m2, I find it is hard to transfer data.

I want use Callable object, but I have many information store in request. how to fetch them inside my new callable object?

my part of code like below：

Code:

---

@RequestMapping(value="/addimages", method=RequestMethod.POST)
        public @ResponseBody Callable<String> postImages(HttpServletRequest request,  Model model, @ModelAttribute("pbid") UUID pbid) {
                //UUID pbid=(UUID) request.getSession().getAttribute("pbid");
                return new Callable<String>() {
                        public String call() throws Exception {
                CommonsMultipartResolver mrs=new CommonsMultipartResolver(request.getSession().getServletContext());
                if (mrs.isMultipart(request)){
                //MultipartHttpServletRequest multipartRequest = mrs.resolveMultipart(request);
                MultipartHttpServletRequest multipartRequest= (MultipartHttpServletRequest) request;
                List<MultipartFile> npl=multipartRequest.getFiles("fileinput");

The java compile give me error is:

Cannot refer to a non-final variable model inside an inner class defined in a different method

ps: I some time meet java.util.ConcurrentModificationException when I do some server part. Is that the problem of spring 3.1.2. release？
