My project
Basically I have two jsp files with forms.

second.jsp ; controller is SecondController ; form view = second ; success view = third ; form method='post' action='second.html'
third.jsp ; controller is ThirdController ; form view = third ; third view = fourth ; form method='post' action='third.html'

third.jsp correctly displays the data submitted in second.jsp. But if I try to add another form into third.jsp, I get errors saying the bean doesn't exist.

The Error
If on "second.html" page, I submit a form, I get this error :
"Neither BindingResult nor plain target object for bean name 'thirdBean' available as request"

Why is the "thirdBean" not being created?

What works
If I go directly to URL "localhost:8080/third.html", then I don't get any errors. The "thirdBean" is created and binding occurs correctly.

What could be wrong?
When I go to "third.html" directly, the thirdBean object is created correctly. But when I go through "onSubmit" of SecondController, then the thirdBean object is not created.
So I suspect that I need to change something in onSubmit

Code samples
SecondController
protected ModelAndView onSubmit(…) {
SecondGreeting cmd =(SecondGreeting)command;
return new ModelAndView("third", "command", cmd);
}

Third.jsp

<spring:bind path="thirdBean.maindish">
Maindish: <input type="text" name="maindish" value="<c:out value="${status.value}"/>">
<font color="red"><c:out value="${status.errorMessage}"/></font>
</spring:bind> <br>
