hop of those help? AFAIK, you can only bind a form with a single object. If you have two classes, then you can create a single class that references the other two classes and then bind with that class.

it should still fix some issue You can't attach more than one object to the
. However, you can create an explicit model class for the form and attach it.
code :
class UpdateUserFormModel {

  private Updateuser updateuser;

  private Facebook facebook;

  private Twitter twitter;

<sf:input type="text" name="firstName" path="updateuser.firstName"/></br>
<sf:input type="text" name="facebook" path="facebook" /> </br>

this one helps. Whenever there is such a if-statement that "split" the complete controller method, like yours, I have the feeling that one controller method should been replaced by two methods, one for each case.
The easiest, and most straight forward solution would been using two different URLs.
code :
@RequestMapping(value = "/section/add",
                method = RequestMethod.POST
public boolean addSection(@ModelAttribute("section") Section section) {...}

@RequestMapping(value = "/section/add",
                method = RequestMethod.POST
public boolean addGroupSection(@ModelAttribute("section") Section section) {...}

I wish this help you It's documented in Spring Framework's documentation:
code :
@SessionAttributes(value = {"user1", "user2"})
public class MyController {
    // ...

    public String page1(ModelMap model){
        model.put("user", new User());
        return "page1";

    public String page1Post(@ModelAttribute("user") User user, ModelMap model{
        model.put("user1", user);
        model.put("user", new User());
        return "page2";

    public String page2Post(@ModelAttribute("user") User user, ModelMap model{
        model.put("user2", user);
        return "page3";

<input type="password" name="password">

<input type="text" name="username">
<label for="email">e-mail :</label>
<input type="text" name="email">

<input type="submit" name="submit" value="submit"/>
<form:form method="post" action="/register" modelAttribute="user">
    <form:label path="loginid">ID:</form:label>
    <form:input path="loginid" />

    <form:label path="password">password:</form:label>
    <form:input path="password" />
