Lets assume your application looks like this:
public class QuestionAndAnswers {
private Question question;
private List<Answer> possibleAnswers;
}
public class AnsweredQuestion {
private Question question;
private Answer answer;
}
public interface WebService {
public List<QuestionAndAnswers> getQuiz(String quizId);
}
I think I'd do it like this
public class Page {
@Inject
private WebService webService;
@Property
private List<AnsweredQuestion> answeredQuestions;
@Property
private AnsweredQuestion current;
private Map<Question, List<Answer>> answerMap;
public SelectModel getSelectModel() {
List<Answer> possibleAnswers = answerMap.get(current);
return createSelectModel(possibleAnswers);
}
public ValueEncoder<AnsweredQuestion> getEncoder() {
// this will be used to serialize/deserialize each value to a hidden
value in the form
}
public void onPrepareRender() {
List<QuestionAndAnswers> qsAndAs = webService.getQuiz(String quizId);
// initialize answeredQuestions
// initialize answerMap
}
}
tml
<t:loop source="answeredQuestions" value="current" encoder="encoder">
${current.question.question}
<t:select value="current.answer" model="selectModel" />
</t:loop>
