PrimeFaces的 p:commandButton在 p:confirmDialog中将ajax设置为false时不会触发action

前端开发 2026-07-11

我有一个基本需求，使用PrimeFaces的 p:confirmDialog来提问一个简单的是/否问题。最初的想法是使用p:commandButton ajax="true"，调用一个动作来更新状态并停留在同一页（使用PF的 @form UI更新+ 向用户显示消息）：

<p:confirmDialog global="true"
                 showEffect="fade"
                 hideEffect="fade"
                 responsive="true"
                 style="max-width: 1000px;">
  <p:commandButton value="No"
                   styleClass="ui-button-secondary ui-confirmdialog-no"
                   type="button" />
  <p:commandButton value="Yes"
                   ajax="true"
                   action="#{ergebnisTextbausteinStatusBean.finalizeStatus()}"
                   process="@this"
                   update="@form template_msg_summary"
                   styleClass="ui-confirmdialog-yes" />
</p:confirmDialog>

这按预期工作。动作被调用，数据库中的状态被更新，UI显示一切正常。

现在客户决定改变这个流程，在Yes时导航到另一页（如果成功的话）。

因此，选择尝试一个 <p:commandButton ajax="false">（因为在整个项目中都在使用，所以这个按钮的代码基本上是从项目中其他地方调整而来）。

对话框+ 使用 ajax="false" 的按钮：

<p:confirmDialog global="true"
                 showEffect="fade"
                 hideEffect="fade"
                 responsive="true"
                 style="max-width: 1000px;">
  <p:commandButton value="No"
                   styleClass="ui-button-secondary ui-confirmdialog-no"
                   type="button" />
  <template:formElementSpacer elementWidth="6" elementWidthM="2" />
  <p:commandButton value="Yes"
                   ajax="false"
                   action="#{ergebnisTextbausteinStatusBean.finalizeStatus()}"
                   styleClass="ui-confirmdialog-yes" />
</p:confirmDialog>

然而，动作从未被调用。

随后我安装了一个JSF PhaseListener（在faces-config.xml中挂接）来检查一些事情：

public class AnyPhaseListener implements PhaseListener {

    @Override
    public PhaseId getPhaseId() {
        return PhaseId.ANY_PHASE;
    }

    @Override
    public void beforePhase(PhaseEvent event) {
        System.out.println("----------------- " + getClass().getSimpleName() + " BEFORE PHASE: " + event.getPhaseId());
    }

    @Override
    public void afterPhase(PhaseEvent event) {
        System.out.println("----------------- " + getClass().getSimpleName() + " AFTER PHASE: " + event.getPhaseId());
    }
}

它会打印出每个请求访问的所有阶段。

对于上面这个（工作中的）AJAX true按钮，记录的系统输出如下：

请注意对 finalizeStatus() 的调用，以及我在动作方法中放入的2-3-4-5条系统输出。

AJAX false按钮的输出则不同：

这完全没有系统输出，这个输出让我看到中间缺少一个完整的请求。

不知道另外两个请求，一个在前一个在后，但我们假设它们没问题。

这里的代码/解决方案有什么问题？

我们是在一台较旧的WebSphere 9服务器上，使用JSF 2.2和 PrimeFaces 13.0.10

解决方案

这里有两个注意点。

首先，需要用 ajax=false 和 action="#{...}" 声明显示对话框的按钮，并使用一个嵌套的 p:confirm（见下方PF bug的代码示例）：

然后（第二点）然而，PrimeFaces 13会触发以下bug：

https://github.com/primefaces/primefaces/issues/12718

为了解决这个问题，根本不要使用 p:confirm：

    <p:commandButton value="Do this"
                     type="button"
                     onclick="PF('myDialog').show();" />

在 p:confirmDialog 上使用一个经典的 widgetVar=""，删除 global="true"，手动调用 PF('myDialog').show() 和 PF('myDialog').hide()，并让对话框中的按钮调用动作：

    <p:confirmDialog widgetVar="myDialog"
                     header="Security Check"
                     message="Lala"
                     responsive="true" >
        <p:commandButton value="No"
                         type="button"
                         onclick="PF('myDialog').hide();" />
        <p:commandButton value="Yes"
                         ajax="false"
                         action="#{statusBean.doSomething()}" />
    </p:confirmDialog>
