How to restore the pre-selected values in the form if there is error while submitting it?

Question

This is my controller code.

@RequestMapping(value = "/save", method = RequestMethod.POST)
public final String submit(@ModelAttribute("loanType") @Valid  LoanType loanType,   
BindingResult binding, RedirectAttributes attr, HttpSession session) {

    if (binding.hasErrors()) {
        attr.addFlashAttribute("org.springframework.validation.BindingResult.loanType",  
binding);
        attr.addFlashAttribute("loanTypeForm", binding);
        return "redirect:/loanType/addLoanType";
    }
       loanTypeService.insertLoanType(loanType);
       log.info("loan type saved succesfully with loan type id =" + 
loanType.getLoanTypeId() + " and name =" + loanType.getLoanTypeName());
       attr.addFlashAttribute("message", "Loan Type named= '" + 
loanType.getLoanTypeName() + "' is added Successfully");


    return "redirect:/loanType/listLoanType";
 }

This is my view page.

         <tr>
         <td>&nbsp;</td>
         <td><form:input cssErrorClass="errorinput" path="loanTypeName"                
               alt="LoanTypeName"     placeholder="Loan Type Name:" /></td>  
         <td><form:errors path="loanTypeName" cssClass="error"/> 
         </td>

         </tr>  

         <tr>
          <td>&nbsp;</td>
            <td><br>
            <table class="form-subtable">
            <tr>
             <td class="formtitle-subtitle">
                     Loan Details
                </td>
             </tr>
             <tr>
               <td><form:errors path="documents"  cssClass="error"/></td>
             </tr>
             <tr>
               <td><form:checkboxes cssClass="regular- checkbox" path="documents"  
                     items="${documentList}" itemLabel="documentName"  
                     itemValue="documentId" delimiter="<br>"/>                                                   
               </td>

           </tr>

         </table>
       </td>
       <td>&nbsp;</td>

         </tr>
         <tr>  
        <td></td>  
        <td>
          <br><div class="submit"><input  class="submit" type="submit" value="Save" />
                <input type="reset" value="Cancel" /></div>
                     </td>
                       <td></td>

                            </tr>
   </table>

When I submit the form without filling the text field and only choosing the checkboxes, it shows the error messages but the previoulsy selected checkboxes gets dis-selected...I want them selected when the controller returns the error messages...

Can anyone help me?

Try

return "loanType/addLoanType";

instead of

return "redirect:/loanType/addLoanType";

OR add command/model as flash attribute

redirectAttributes.addFlashAttribute("loanType", loanType);

redirect is a complete new request and anything stored in existing request will be destroyed.

you can do it manually in your controller redirect to the previous page if there is an error and save request scope attribute that you want to return

@RequestMapping(value = "/save", method = RequestMethod.POST)
public final String submit(@ModelAttribute("loanType") @Valid  LoanType loanType, BindingResult binding, RedirectAttributes attr, HttpSession session,HttpServletRequest request) {

if (binding.hasErrors()) {

//set request scope attribute ex name
request.setAttribute("name","testName");
    return "redirect:/loanType/addLoanType";
}
   loanTypeService.insertLoanType(loanType);
   log.info("loan type saved succesfully with loan type id =" + loanType.getLoanTypeId()+ " and name =" + loanType.getLoanTypeName());
   attr.addFlashAttribute("message", "Loan Type named= '" + loanType.getLoanTypeName() + "' is added Successfully");


return "redirect:/loanType/listLoanType";
 }

and on your jps page retrieve the attribute with EL.

<form:input path="Name" alt="Name"     placeholder="Name:" value="${name}" />
