Dear All
I use JDO with spring
and when i add @ModelAttribute("countries")
All things go fine except the data not saved without any exception
When query from another datastore
@Controller
public class PortController {
private static final String FORM_MODEL_KEY = "ports";
private static final String FORM_UPDATE_KEY = "port/Edit";
private static final String REDIRECT_LIST_VIEW_KEY = "redirect:/port/
home.htm" ;
@Autowired
private PortDAO portDAO;
@Autowired
private CountryDAO countryDAO;
public PortController() {}
@InitBinder
protected void initBinder(HttpServletRequest request,
ServletRequestDataBinder binder) throws Exception {
binder.registerCustomEditor(String.class, new
StringTrimmerEditor(false));
binder.registerCustomEditor
(com.xesolution.domain.Country.class, new CountryEditor(countryDAO));
}
@RequestMapping(value="/port/home.htm")
public ModelMap list() {
return new ModelMap(FORM_MODEL_KEY,portDAO.readAll());
}
@RequestMapping(value="/port/new.htm")
public ModelAndView create(){
Port port = new Port();
return new ModelAndView(FORM_UPDATE_KEY,FORM_MODEL_KEY,port);
}
@RequestMapping(value="/port/update.htm")
public ModelAndView update(@RequestParam("id") String id) {
Port result = portDAO.read(id);
return new ModelAndView(FORM_UPDATE_KEY,FORM_MODEL_KEY, result);
}
@RequestMapping(value="/port/save.htm", method = RequestMethod.POST)
public ModelAndView save(@ModelAttribute(FORM_MODEL_KEY) Port port,
BindingResult result, SessionStatus status) {
new PortValidator().validate(port, result);
if (result.hasErrors())
{
return new ModelAndView(FORM_UPDATE_KEY, FORM_MODEL_KEY,
port);
}
else
{
portDAO.persist(port);
return new ModelAndView(FORM_UPDATE_KEY, FORM_MODEL_KEY, port);
return new ModelAndView(REDIRECT_LIST_VIEW_KEY, list());
}
}
@ModelAttribute("countries")
public List<?> populateCountry() {
//this make data not saved
return countryDAO.readAll();
//But this make the data saved
//return portDAO.readAll();
}
public void setPortDAO(PortDAO portDAO) {
this.portDAO = portDAO;
}
}
and this is jsp line which display the form select
<form:select path="country" items="${countries}" itemLabel="name"
itemValue="id"/>
