java - Spring MVC multiple rows form submit submits new ModelAttribute -

ok 1 of spring's null modelattribute i've tried found doesn't work.

i've adding tutorials functionality web app spring-mvc everythings workds greate except when have data form bean.

i use 2 post methods

@requestmapping(method = requestmethod.post)     public string openedit(@requestparam("notfound") string[] notfound,                            model model){         editform editform = editmodel.createeditform(notfound);         model.addattribute("editform",editform);         return "edit/editowners";     }      @requestmapping(method = requestmethod.post,value = "/saveowners")     public string saveowners(@modelattribute("editform") editform editform){         editmodel.addowners(editform);         return "index";     } 

the first 1 works fine , can see data in jsp, second 1 gets new modelattribute.

this form

<form:form method="post" action="saveowners" modelattribute="editform" >             <table class="table table-bordered table-striped table-hover table-condensed">                 <caption>                     <h4>edit owners</h4>                 </caption>                 <thead>                 <tr>                     <td>name</td>                 </tr>                 </thead>                 <tbody>                 <c:foreach items="${editform.owners}" var="item" varstatus="status">                     <tr>                         <td>${item.name}</td>                         <td><input type="text" name="${owners[status.index].outid}" value="${item.outid}" /> </td>                         <td><input type="text" name="${owners[status.index].type}" value="${item.type}" /> </td>                     </tr>                 </c:foreach>                 </tbody>             </table>             <input type="submit" value="save" class="btn btn-primary"/>         </form:form> 

what seems wrong here ? ps tried inputs , without type attribute , still gets null, , said can see data can't submit them.

have tried adding following annotation top of controller class ?

@sessionattributes({ "editform" }) public class yourcontroller {  ... }
