How to clear form fields after submit

[saurabh.17]

Hi Everyone,

I have a simple form with some fields on a jsp page. After submitting the page I am showing the same page. But the page is not clearing the field values. I want them to clear after submitt the page.

Thanks for any help.

After submit, if you are trying to get the same page, you need to redirect the the page to get the new form.

The new from gets populated from the object created in formBackingObject method.

Could you post your controller code?

Hi sixseasons,

Thanks for your reply. This is my controller code -

public class AddressController extends SimpleFormController {

    private StateDao stateDao;
    private AddressManager addressManager;

    private static final String ADDR_ID = "id";

    public AddressController(StateDao stateDao,
            AddressManager addressManager) {
        this.stateDao = stateDao;
        this.addressManager = addressManager;
    }

    protected Object formBackingObject(HttpServletRequest request) throws Exception {

          CustomerAddress command = null;
          command = new CustomerAddressImpl();
          command.clearValues();  // I found this way from the forum. 

          return command;
    }

    protected ModelAndView onSubmit(HttpServletRequest request, HttpServletResponse response, Object command,
        BindException errors) throws Exception {

        CustomerAddress custAddr = (CustomerAddress) command;
        custAddr.setUserId(1);
        Address addr = addressManager.getAddress(1);
        addressManager.addAddress(custAddr, addr);

        Map model = errors.getModel();

        model.put("addresses", getAllAddresses());
        model.put("states", getStatesRefData());

        CustomerAddress newAddr = new CustomerAddressImpl();
        model.put(this.getCommandName(), newAddr);
        return new ModelAndView(this.getSuccessView(), model);
    }

    private List getStatesRefData() {
        return stateDao.readStatesByCountry("US");
    }
    
    private List getAllAddresses() {
    	return addressManager.getAllAddresses(1);
    }
}

In a forum I found a way for doing the same, but it's not working. They have adviced to make a clearValues() method in command object and call it in formBackingObject () method.

Thanks

My suggestions:
1. use referenceData method for addresses and states.
2. use redirectview to get the new form in onSubmit method.
3. In formbackingObject method, you are already creating new object, that's enough. No need to 'clearValues'.
