我有一个问题，我的 AJAX 请求没有在 JSF 中触发，原因不明。
admin.xhtml 片段：
<h:form id="adminPanel">
...
<f:subview id="editCustomer#{customer.id}">
<p class="#{adminService.getEditCustomerClass(customer.id)}">
<h:inputText id="email#{customer.id}" value="#{adminService.customerEmail}"/><br/>
<h:inputText id="firstName#{customer.id}" value="#{adminService.customerFirstName}"/>
<h:inputText id="lastName#{customer.id}" value="#{adminService.customerLastName}"/><br/>
<h:commandButton id="saveEdit#{customer.id}" type="button" value="Save">
<f:ajax render="@form" event="click" listener="#{adminService.saveCustomer()}"/>
</h:commandButton>
<h:commandButton id="cancelEdit#{customer.id}" type="button" value="Cancel">
<f:ajax render="@form" event="click" listener="#{adminService.cancelEdit()}"/>
</h:commandButton>
</p>
</f:subview>
...
</h:form>
AdminService.java 片段：
@Named
@Stateless
@LocalBean
public class AdminService {
public String getEditCustomerClass(int id) {
return id != customerId ? "hidden" : "";
}
public void saveCustomer() {
cancelEdit();
}
public void cancelEdit() {
movieId = -1;
customerId = -1;
orderId = -1;
actorId = -1;
employeeId = -1; //if none of the id's match, p should return 'hidden' class and not be seen.
}
}
最初我遇到了问题，因为我没有使用 CSS 隐藏和显示，而是使用了“rendered=”属性。但是，我听说视图的部分渲染会破坏 AJAX，所以我将它逐步淘汰，希望不部分渲染视图（仅隐藏和显示它）可以解决问题。
然而，这个 ajax 仍然没有调用我在 listener 属性中指定的方法（整个页面要大得多，并且使用更多的 AJAX，尽管其余部分在按下这些按钮之前工作，然后其他 ajax 按钮停止响应。）
如果我将按钮类型更改为提交，如果我按下按钮两次，它实际上会执行侦听器方法，但是其他 ajax 链接不会调用它们各自的侦听器方法。
我怎样才能让它工作？

更新 2：
当我切换到没有 AJAX 的“提交”类型的命令按钮时，它按预期工作（除了某些按钮需要单击两次才能激活）。所以问题被本地化为 f:ajax 标签。
更新 3：
admin.xhtml 的整个代码库。它有点不干净，因为它正在被调试并尝试使其工作的过程。
