Spring 3 -- IllegalStateException

[Frank Serkland]

I'm getting an IllegalStateException in a Spring application. Here is the form.

<form:form action="poll1" modelAttribute="poll1" method="post">
    <table>
          <tr>
              <td><b><i>Poll #1</i></b></td>
          </tr>
          <tr>
              <td>Would you like to have a 30-year reunion in 2016?<br>
          </td>
          </tr>
          <tr>
              <td><form:radiobutton path="vote" value="yes" />Yes
                  <form:radiobutton path="vote" value="no" />No</td>
          </tr>
          <tr>
              <td><input name="submit" type="submit" value="Vote Poll #1" align="left" /></td>
          </tr>
      </table>
</form:form>

Here is my controller, for what it's worth.

@RequestMapping(value = "/poll1", method = RequestMethod.POST)
public String processPoll1(@RequestParam String vote, Model model) {
    poll1DAO.tallyVote(vote);
    model.addAttribute(new Cookie("poll1", "voted"));
    return "PollPage";  
}

I'm doing this when I call the page.

@RequestMapping(value = "/polls") 
public String polls(Model model) {
    model.addAttribute("poll1", new Poll1());
    return "PollPage";
}

And yet I still get this error.

Hi Frank,

If you need the poll1 to be there in between requests, you can use @SessionAttributes.

In your case, you can put something like below.

@Controller 
@SessionAttributes("poll1")
public class AcmeForm {

- k
