Question

我的目的是在BD中插入记录后在rich：popupPanel中向用户显示一条消息。

使用下面的代码，我可以做我想要的，但有问题。仅在我正确键入所有页面字段时才有效。如果其中一个字段未通过验证，则验证消息将显示在h：消息中，即使我更改了字段的内容并再次单击该按钮，页面也不会更改。

可能出现什么问题？

页

<h:outputLabel value="Nome:" for="nome1" />
<h:inputText id="nome1" maxlength="50" required="true" requiredMessage="Informe um nome" immediate="true"/>

<h:outputLabel value="Logradouro:" for="logradouro" />
<h:inputText id="logradouro" maxlength="50" required="true" requiredMessage="Informe o logradouro" immediate="true"/>

<h:outputLabel value="Bairro:" for="bairro" />
<h:inputText id="bairro" maxlength="45" required="true" requiredMessage="Informe o bairro" immediate="true" />

<h:outputLabel value="CEP:" for="cep" />
<h:inputText id="cep" maxlength="8" required="true" requiredMessage="Informe o CEP" immediate="true">
    <f:convertNumber integerOnly="true" groupingUsed="false" maxIntegerDigits="8" />
</h:inputText>

<a4j:commandButton id="btnInserirDizimista" value="Inserir" oncomplete="#{rich:component('pnlOk')}.show()" render="pnlMessages outPnlOk" actionListener="#{dizimistaMB.inserirDizimista}"/>

<a4j:outputPanel id="outPnlOk" ajaxRendered="true">
<rich:popupPanel id="pnlOk" modal="true" height="150">
        <h:graphicImage value="/images/info.jpg" />
        <h:outputText id="textoModalOk" value="#{dizimistaMB.textoModal}" />
        <h:commandButton value="OK" action="dizimista?faces-redirect=true"
            onclick="#{rich:component('pnlOk')}.hide(); return false;" >
            <a4j:ajax execute="formPnlOk" />
        </h:commandButton>
    </rich:popupPanel>
</a4j:outputPanel>

托管bean

public void inserirDizimista(){
    try{
        defineDizimista("formNovoDizimista");
        dizimistaFacade.criar(dizimista);
        setTextoModal("Dizimista inserido com sucesso");
        System.out.println("Dizimista '" + dizimista.getNome1() + "' inserido com sucesso");
        dizimista = null;
    } catch (DAOException e) {
        FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_ERROR, e.getMessage(), null);
        JSFHelper.getFacesContext().addMessage("ATENÇÃO!", msg);
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

private void defineDizimista(String nomeForm){
    Map<String, String> dados = getDadosFormulario(nomeForm);
    dizimista.setNome1(dados.get("nome1"));
    dizimista.setLogradouro(dados.get("logradouro"));
    dizimista.setBairro(dados.get("bairro"));
    dizimista.setCep(Integer.parseInt(dados.get("cep")));
}

private Map<String, String> getDadosFormulario(String form){
    Map<String, String> dados = new HashMap<String, String>();
    dados.put("nome1", JSFHelper.getRequestParameter(form +
        UINamingContainer.getSeparatorChar(JSFHelper.getFacesContext()) + "nome1"));
    dados.put("logradouro", JSFHelper.getRequestParameter(form +
        UINamingContainer.getSeparatorChar(JSFHelper.getFacesContext()) + "logradouro"));
    dados.put("bairro", JSFHelper.getRequestParameter(form +
        UINamingContainer.getSeparatorChar(JSFHelper.getFacesContext()) + "bairro"));
    dados.put("cep", JSFHelper.getRequestParameter(form +
        UINamingContainer.getSeparatorChar(JSFHelper.getFacesContext()) + "cep"));
    dados.put("cidade", JSFHelper.getRequestParameter(form +
        UINamingContainer.getSeparatorChar(JSFHelper.getFacesContext()) + "cidade"));
    return dados;
}

当您通过AJAX呈现rich:popupPanel的内容（从a4j:commandButton呈现）时，最好选择使用its show attribute有条件地显示内容，而不是调用Javascript代码（oncomplete））。

所以，我建议您添加显示popupPanel的条件。假设textoModal在初始化时为null，并且您的bean是请求作用域，您可以使用以下内容：

<rich:popupPanel id="pnlOk" modal="true"
       show="#{dizimistaMB.textoModal != null}" ...>

_{您可能希望在辅助bean中创建一个类似public boolean isShowTextoModal()的方法，它可以实现更好的规则，而不仅仅是检查字段是否为空。}

然后，您可以将按钮更改为：

<h:commandButton id="btnInserirDizimista" value="Inserir"
       render="pnlMessages outPnlOk"
       action="#{dizimistaMB.inserirDizimista}" />

...并从方法ActionEvent中移除inserirDizimista参数，使其成为action method instead of a actionListener。

这应该让事情顺利进行。

验证和丰富：popupPanel不起作用
