Changed values aren't set on the backing object.

I have an "issue" which contains 0-* "responses". However when I edit the issue the updates aren't being returned from the .jsp . I'm using Spring, and that might be the problem, but I think it's a JSP issue.

Here's my controller:

public class AddResponseFormController extends SimpleFormController 
{ 
� � protected final Log _logger = LogFactory.getLog(getClass()); 
 
� � private Bucket bucket; 
 
� � public ModelAndView onSubmit(Object command) 
� � { 
� � � � _logger.info("submitted new response."); 
� � � � Response response = (Response)command; 
 
� � � � Issue issue = response.getIssue(); 
� � � � _logger.info(new StringBuffer().append("Adding a response to issue (").append(issue.getName()).append(") to the bucket.").toString()); 
 
� � � � issue.getResponses().add(response); 
� 
// CHANGES MADE IN THE JSP (SEE BELOW) DON'T GET HERE! 
� � � bucket.save(issue); 
 
� � � � Map myModel = new HashMap(); 
� � � � myModel.put("Issue", issue); 
� � � � return new ModelAndView(new RedirectView(getSuccessView()), myModel); 
� � } 
� � 
� � protected Object formBackingObject(HttpServletRequest request) 
� � { 
� � � � _logger.info("about to create a new response."); 
� � � � Response response = new Response(); 
� � � � Issue parent = bucket.getSplash(Integer.parseInt(request.getParameter("issueId"))); 
� � � � response.setIssue(parent); 
� � � � response.setResponseBy(request.getRemoteUser()); 
� � � � _logger.info("response by = " + response.getResponseBy()); 
� � � � return response; 
� � } 
 
� � public void setBucket(Bucket bucket){this.bucket = bucket;} 
}

And here's my JSP:

The new response is created correctly: the two fields from issue you can edit at the same time do not however get passed back as changed to the controller.

Any ideas why?
