Selectoneradio sending only one value

Question

I am concluding a simulation system for my course completion work. However, I have a problem that I have not yet been able to solve.

I perform a filter to select the questions for the user to answer, and set those questions that were found by the filter within a List. However, when the student answers these questions selectOneRadio only takes the last value and not all the answers values to make the comparison.

Can someone help me?

Follows the related codes:

Filter:

    public class SimuladoFiltroDAO implements Serializable {

        private static final long serialVersionUID = 1L;

        @Inject
        private EntityManager manager;

        @SuppressWarnings("unchecked")
        public List<Questao> geraSimuladoPorFiltro(Long codigoCurso,
                Integer complexidade, Integer numeroDeQuestoes) {
            String query = "SELECT NEW com.sisEnade.tcc.modelo.Questao(q.codigo, q.pergunta, "
                    + "q.respostaPadraoPerguntaItem) FROM Questao q "
                    + "WHERE CURSO = ?1 AND complexidade = ?2";
            List<Questao> questoes = manager.createQuery(query)
                    .setParameter(1, codigoCurso).setParameter(2, complexidade)
                    .setMaxResults(numeroDeQuestoes).getResultList();
            for (Questao questao : questoes) {
                System.out.println(questao.getCodigo());
                System.out.println(questao.getPergunta());
                System.out.println(questao.getRespostaPadraoPerguntaItem());
            }
            return questoes;
        }

Simulado Bean: 

@Named
@ViewScoped
public class GerarSimuladoBean implements Serializable {

    private static final long serialVersionUID = 1L;

    @Inject
    SimuladoFiltroDAO simuladoFiltroDAO;

    @Inject
    private RespostaService respostaService;

    private Curso cursoSelecionado;
    private Integer complexidadeSelecionada;
    private Integer numeroDeQuestoesSimulado;
    private Resposta resposta = new Resposta();

    private List<Questao> questoes;

    @Transactional
    public void gerarSimulado() {
        this.questoes = simuladoFiltroDAO.geraSimuladoPorFiltro(
                cursoSelecionado.getCodigo(), this.complexidadeSelecionada,
                this.numeroDeQuestoesSimulado);
        this.resposta.setQuestao(questoes);
    }

    @Transactional
    public void enviar() {
        this.respostaService.salvar(resposta);
        FacesUtil.addSuccessMessage("Resposta salva com sucesso");
    }

    public Curso getCursoSelecionado() {
        return cursoSelecionado;
    }

    public void setCursoSelecionado(Curso cursoSelecionado) {
        this.cursoSelecionado = cursoSelecionado;
    }

    public Integer getComplexidadeSelecionada() {
        return complexidadeSelecionada;
    }

    public void setComplexidadeSelecionada(Integer complexidadeSelecionada) {
        this.complexidadeSelecionada = complexidadeSelecionada;
    }

    public Integer getNumeroDeQuestoesSimulado() {
        return numeroDeQuestoesSimulado;
    }

    public void setNumeroDeQuestoesSimulado(Integer numeroDeQuestoesSimulado) {
        this.numeroDeQuestoesSimulado = numeroDeQuestoesSimulado;
    }

    public List<Questao> getQuestoes() {
        return questoes;
    }

    public void setQuestoes(List<Questao> questoes) {
        this.questoes = questoes;
    }

    public Resposta getResposta() {
        return resposta;
    }

    public void setResposta(Resposta resposta) {
        this.resposta = resposta;
    }

}   

Here is an image of my most detailed problem, I get a list of questions and answer two questions only it only sends one answer and not both.

XHTML From the stretch involved:

<p:dataTable id="exibePerguntas" var="questao"
                value="#{gerarSimuladoBean.questoes}" >
                <p:column headerText="Perguntas">
                    <br></br>
                    <p:outputLabel value="#{questao.pergunta}" />
                    <p:selectOneRadio id="resposta" style="width:25%" value="#{gerarSimuladoBean.resposta.respostaItem}">
                        <f:selectItem itemLabel="A" itemValue="A" />
                        <f:selectItem itemLabel="B" itemValue="B" />
                        <f:selectItem itemLabel="C" itemValue="C" />
                        <f:selectItem itemLabel="D" itemValue="D" />
                    </p:selectOneRadio>
                </p:column>
            </p:dataTable>
            <p:commandButton id="enviarSimulado" value="Enviar Simulado"
                    action="#{gerarSimuladoBean.enviar}" icon="ui-icon-search"
                    iconPos="right" update=":frmCadastroSimulado">
                </p:commandButton>

Valeus!

You can try to do how are you here.

Create a Question and Answer Map... instead of assigning the variable resposta.respostaItem, Voce creates a Map<Pergunta, Resposta> selectedOptions . That’s where the assignment goes:

<p:selectOneRadio value="#{gerarSimuladoBean.selectedOptions[question]}">
