I have code:

<display:table name="sessionScope.allUserslist" id="userList"  export="false"  pagesize="1">
    <display:column title="Select" style="width: 90px;">
        <input type="checkbox" name="optionSelected" value="<c:out value='${userList.loginName}'/>"/>
    </display:column>
    <display:column property="loginName" sortable="false" title="UserName" paramId="loginName" 
     style="width: 150px; text-align:center" href="./editUser.do?method=editUser"/> 
    <display:column property="role" sortable="false" title="UserRole" paramId="role" 
     style="width: 150px; text-align:center"/>
</display:table>            

On click of login name, I am moving to a new page where I need to get all the of user, I am just getting the name not the role, on click of link I am calling an action where in the method I am trying to read the data from the form using

User u=(User)form;
u.getRole();

but it's null. Where am I going wrong ?
