Row not updating - Update button within dialog (opened by button within dataTable)

Question

Versions: PrimeFaces 3.5, JPA 2.1, GlassFish 4.0, Java EE 7, JSF 2.0.

Dialog normally opens and displays data for edition, but the "Update" button in this dialog is not working. Button code follows:

<p:commandButton actionListener="#{funcionarioMB.save}"
                                     value="Alterar"
                                     oncomplete="dlg.hide();"
                                     update=":tblFuncionarios"
                                     ajax="false" />

Full dialog code:

<p:dialog id="dlg"
              header="Editar funcionário"
              modal="true"
              widgetVar="editarDialog"
              closable="true"
              draggable="false"
              appendToBody="true"
              maximizable="false"
              minimizable="false"
              position="center"
              resizable="false"
              showEffect="slide">
        <p:outputPanel>
            <h:form id="formAlterar">
                <h:panelGrid id="infosFuncionario">

                    <!-- inputs -->

                    <p:commandButton actionListener="#{funcionarioMB.save}"
                                     value="Alterar"
                                     oncomplete="dlg.hide();"
                                     update=":tblFuncionarios"
                                     ajax="false" />
                </h:panelGrid>
            </h:form>
        </p:outputPanel>
    </p:dialog>

Update commandButton within the dataTable:

<h:form>
                <p:commandButton actionListener="#{funcionarioMB.prepareEdit(funcionario.id)}"
                                 value="alterar"
                                 oncomplete="editarDialog.show();"
                                 update=":formAlterar" />
            </h:form>

Method save() in the managed bean:

public void save() {
    Cargo cargo = this.cargoRepositorio.findById(this.cargoID);
    funcionario.setCargo(cargo);

    if (this.getFuncionario().getId() == null) {
        this.funcionarioRepositorio.add(this.getFuncionario());
    } else {
        this.funcionarioRepositorio.edit(this.getFuncionario());
    }
    this.funcionario = new Funcionario();
    this.funcionarios = null;
}

Method edit() in the repository:

public void edit(Funcionario funcionario) {
    this.manager.merge(funcionario);
}

And the button for updating the entity doesn't work without ajax="false".

Also didn't work using JDBC connection. – Rasshu Nov 30 '13 at 20:29 — Rasshu, Nov 30 '13 at 20:29

where is your datatable ?

just recreate/rebuild your datatable value.

in your managedbean/backing bean add this method after CRUD operation execute

public List<T> refreshDatatable(){
    list=yourEJBFacade().getList();
    return list
}

in your session bean

public List<T> getList(){
 Query q = entityManager.createQuery("select a from YourEntityClass a");
 return q.getResultList();
}

update your datatable (update=":tblFuncionarios")

for references see this question at Primefaces datatable Reset and Reload data

Thanks, but the datatable is refreshing correctly; the edited row isn't updating in the database. – Rasshu Dec 01 '13 at 20:57
I got it working adding ActionEvent actionEvent as "save" method's parameter. – Rasshu Dec 04 '13 at 12:26

Added ActionEvent actionEvent as save method's parameter and now it's working, thanks to Erick R. Ribeiro's hint in the PrimeFaces Facebook group.
