My actionListener doesn't work

Question

I have a dialog that is supose to add a object in my arraylist and data base, but my actionListener just don't call my function! I tried to put some prints and no one is called inside my function, but everthing seens to be fine. Anyone can find the problem?

My dialog:

        <p:dialog header="Novo Aluno" widgetVar="novoDialog" modal="true"
        resizable="false">
        <h:form>
            <p:outputPanel>
                <p:panelGrid columns="2">
                    <h:outputText value="Nome: " />
                    <p:inputText value="#{alunosView.alunoNovo.nome}" />
                </p:panelGrid>
                <p:panelGrid columns="1">
                    <p:selectOneMenu value="#{alunosView.alunoNovo.turma}">
                        <f:selectItems value="#{alunosView.turmas}" var="turma"
                            itemLabel="#{turma.curso} - #{turma.ano}º ano" />
                    </p:selectOneMenu>
                </p:panelGrid>
                <p:panelGrid columns="2">
                    <p:commandButton value="Adicionar" update=":form:alunos"
                        actionListener="#{alunosView.adicionarAluno}"
                        oncomplete="PF('novoDialog').hide();" />
                    <p:commandButton value="Cancelar"
                        oncomplete="PF('novoDialog').hide();" />
                </p:panelGrid>
            </p:outputPanel>
        </h:form>
    </p:dialog>

My bean:

@ManagedBean
@ViewScoped
public class AlunosView {
ArrayList<Aluno> alunos;
ArrayList<Turma> turmas;
Aluno alunoSelecionado;
Aluno alunoNovo;
ClassDAO<Aluno> alunoDao;
ClassDAO<Turma> turmaDao;

@PostConstruct
public void init(){
    alunoDao = new ClassDAO<>(Aluno.class);
    turmaDao = new ClassDAO<>(Turma.class);
    alunos = alunoDao.getAll();
    turmas = turmaDao.getAll();
    alunoSelecionado = new Aluno();
    alunoNovo = new Aluno();
}

public void adicionarAluno(){
    System.out.println("asdhaisdisdhisdaisdahiasdhsad dkgsad ksa gdlasds");
    alunoDao.save(alunoNovo);
    alunos = alunoDao.getAll();
}

public void deletarAluno(){
    alunoDao.remove(alunoSelecionado.getId());
    alunos = alunoDao.getAll();
}

public void salvarAluno(){
    alunoDao.save(alunoSelecionado);
    alunos = alunoDao.getAll();
}

public ArrayList<Aluno> getAlunos() {
    return alunos;
}

public void setAlunos(ArrayList<Aluno> alunos) {
    this.alunos = alunos;
}

public ArrayList<Turma> getTurmas() {
    return turmas;
}

public void setTurmas(ArrayList<Turma> turmas) {
    this.turmas = turmas;
}

public Aluno getAlunoSelecionado() {
    return alunoSelecionado;
}

public void setAlunoSelecionado(Aluno alunoSelecionado) {
    this.alunoSelecionado = alunoSelecionado;
}

public Aluno getAlunoNovo() {
    return alunoNovo;
}

public void setAlunoNovo(Aluno alunoNovo) {
    this.alunoNovo = alunoNovo;
}

}

The most stranger thing is that I have other page almost equal to this one and that page and that bean works fine! The code in the post construct method works fine too. Anyone help me?

If the pages are _"almost equal "_ then I'd try to find the differences! — Kukeltje, Sep 02 '16 at 06:48
Just to know, all the solutions mentioned in the post that suppose to have a solution, failed. So, I still have the problem and someone closed my post. I'll make the page with other components, place the button in the page itself instead in a dialog. — Gustavo Mendonça, Sep 06 '16 at 00:54
Please make your code a [mcve]. Most likely the duplicate does contain the solution though — Kukeltje, Sep 06 '16 at 07:03
