Question

我知道嵌套是表单标签的问题。但是，我的页面没有嵌套表单。我有一个表单（id =＆＃34; menuForm＆＃34;）来包含p：菜单。接下来，我在页面下方有一个表单（id =＆＃34; locationForm＆＃34;）。我已经检查了输出的html源代码，并且没有发生嵌套。

我有一个p：commandButton，我想用它来提交表单。它偶尔会起作用，但不是所有的时间。有时，该方法会触发，有时则不会触发。任何人都可以说出我做错了什么吗？

此外 - 如果我完全注释掉菜单表单，它将按预期工作。

感谢。

行动方法：

    public String insertLocationAction(){
    System.out.println("******* Method Fired.");
    DatabaseManager.insertLocation(newLocation);
    return "locations";
    }

请参阅：http://www.primefaces.org/docs/vdl/4.0/primefaces-p/commandButton.html

默认情况下，p：commandButton处理整个视图＆＃39;。

添加流程=＆＃34;：locationform＆＃34;对于commandButton可能只需要＆＃34; locationform＆＃34; （取决于您的选择器工作和嵌套的jsf组件等。
