好的，我这里有问题。我有一个 baseTemplate.xhtml：

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
  xmlns:ui="http://java.sun.com/jsf/facelets"
  xmlns:h="http://java.sun.com/jsf/html"
  xmlns:p="http://primefaces.org/ui"
  xmlns:f="http://java.sun.com/jsf/core">

<h:head>
    <!-- Incluir Scripts e Folhas de Estilo comuns a todas as páginas do sistema -->
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />        
    <h:outputStylesheet library="css" name="default.css"/>
    <h:outputStylesheet library="css" name="cssLayout.css"/>
    <h:outputStylesheet library="css" name="rodape.css"/>


    <title>SisEventos - Sistema de Gerenciamento de Eventos</title>
</h:head>
<h:body>
    <div class="estrutura">
        <div class="top">
        </div>

        <div class="menu">
            <!-- <ui:insert name="menu"> -->
            <h:form id="frmMenu"> 
                <p:menubar autoDisplay="true" >
                    <p:menuitem value="Home" icon="ui-icon-home" url="/paginas/home.xhtml" /> 

                    <p:submenu label="Manutenção" icon="ui-icon-person"> 
                        ...
                    </p:submenu> 

                    <p:submenu label="Atividades" > 
                        ...
                    </p:submenu> 

                    <p:submenu label="Relatórios" > 
                        ...
                    </p:submenu> 

                    <p:submenu label="Evento" > 
                        ...
                    </p:submenu> 

                    <p:menuitem value="Contato" /> 
                </p:menubar>
            </h:form>
        </div>

        <div class="left_content">
            <ui:insert name="content">
            </ui:insert>
        </div>

        <div class="bottom">
           ...
        </div>
    </div>  
</h:body>

和这样的客户页面：

                dlgNovo.hide();
            }
        }
    </script>
</ui:define>

bean中的一个动作如下：

@ManagedBean(name = "eventoBeanTeste")
@SessionScoped
public class EventoBeanTeste {

    ...

    // Listener de cadastro de evento
    public void cadastrarEvento(ActionEvent e) {
        MessageHelper.showGlobalMessage("Fired!", FacesMessage.SEVERITY_INFO);
    }
    ...
}

我的问题是：没有调用 cadastrarEvento 动作监听器！似乎命令按钮不起作用！可能有什么问题？

我了解到将表单放入对话框中是一种很好的做法。如果你这样做，你应该小心不要嵌套表格。所以把它放在你当前的表单“frmEventos”之外。

我猜现在将调用 actionlistener。

看看这个线程：Primefaces Dialog

将命令按钮更改为 并从支持 bean 的函数中删除 ActionEvent 参数。<p:commandButton id="cbNovoSalvar" value="Salvar" action="#{eventoBeanTeste.cadastrarEvento}"
update="@form frmEventos:gMessages"/>
