【问题描述】:
我知道嵌套是表单标签的一个问题。但是,我的页面没有嵌套表单。我有一个表格 (id="menuForm") 来附上 p:menu。接下来,我在页面下方有一个表单 (id="locationForm")。我检查了输出的html源代码,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,但并非一直有效。有时,该方法会触发,而其他时候则不会。谁能指出我做错了什么?
另外——如果我完全注释掉菜单表单,它会按预期工作。
谢谢。
动作方法:
public String insertLocationAction(){
System.out.println("******* Method Fired.");
DatabaseManager.insertLocation(newLocation);
return "locations";
}

如果你把
<p:menu>注释掉,你的意思是? -
我已经尝试了在离开菜单时移除表单 id=menuForm 的不同组合——导致关于缺少表单的 JSF 错误。如果我删除整个东西,
