[Wicket-user] form with listview that contains radio groups?

[Kurt R. Hoehn]

I never really know what to put in the subject, but here is my question.

I'm putting together a series of questions that exist under one profile
and they are simple yes/no radio buttons and the user clicks yes or no
for the question.  I put together the form and it pulls and displays the
information with out error in an edit mode, but when I submit the form
with changes to the questions, they don't seem to make it from the form.

I have been successful with a radio group outside of a listview and the
radio buttons inside the listview, but this is the reverse of that. 

Does Wicket allow this or is there a workaround to this?

Here is my code:

Environment:
   Wicket 1.x branch
   Spring
   Hibernate
   Java 1.5_8
   FirebirdSql
   Ubuntu 6.10 (linux)

Domain Objects:

public class Profile
{
    ...
    private String identity;
    private String name;
    ...
}  

public class SurveyQuestion
{
    ...
    private String identity;
    private String question;
    private Boolean answer;
    ...
}

Wicket Page Object:
public class SurveyPage extends WebPage
{
    ...

    public SurveyPage()
    {
        Questions questions = new Questions();
        questions.setProfile( profileDao.findProfile() );

questions.setQuestions( questionDao.findQuestions(questions.getProfile()));
        CompoundPropertyModel survey = new
CompoundPropertyModel(questions);
        add(new SurveyForm("surveyForm", questions));
    }

    class SurveyForm extends Form
    {
        public SurveyForm(String s, final IModel iModel)
        {
            super(s, iModel);

            ...

            ListView survey = new ListView("survey") {
                protected void populateItem(ListItem listItem) {
                    SurveyQuestion question = (SurveyQuestion)
listItem.getModelObject();

                    listItem.add(new Label("question",
question.getQuestion()));
                    RadioGroup answer = new RadioGroup("answer", new
Model(question.getAnswer()));
                    answer.add(new Radio("true", new Model(true)));
                    answer.add(new Radio("false", new Model(false)));
                    listItem.add(answer);
                }
            };

            survey.setReuseItems(true);
            add(survey);

            ...
        }

        public void onSubmit()
        {
            Profile profile =
((Questions)getModel().getObject()).getProfile();

            PageParameters parameters = new PageParameters();
            parameters.add("identity", center.getIdentity());
            parameters.add("ro", "true");
            setResponsePage(SurveyPage.class, parameters );

            profileDao.makePersistent(profile);
        
            // Doing this to see if the domain object is being updated from the
form.   
            for(Object survey:
((Questions)getModel().getObject()).getSurvey())
            {
                System.out.println( "Answer:  " +
((ProfileSurvey)survey).getAnswer() );
            }
        }
    }
}

class Questions implements Serializable
{
    private Profile profile;
    private List survey;

    ...
}

SurveyPage.html

<form wicket:id="surveyForm">
...
<table>
    <tr wicket:id="survey">
        <td><span wicket:id="question"></span></td>
        <td><span wicket:id="answer">
                <input type="radio" wicket:id="true">Yes&nbsp;<input 
type="radio"
wicket:id="false">No</span>
        </td>
    </tr>
</table>
...
</form>
