我需要一些支持，我不知道会发生什么:
我正在使用 JSF 2 和 Primefaces 来开发一个需要动态创建 MenuBar 的网站，我正在使用动态菜单 Primefaces (MenuModel) 的基本结构:
DefaultMenuModel -> DefaultSubMenu -> DefaultMenuItem
对于我的页面，我正在创建一个 session bean，它负责创建我的菜单(如果有必要)并重新创建(如果有任何更改)，一切都运行良好，我的菜单是使用所有参数(结果)和其他方法(操作)创建的。
我的问题是，当我一次又一次单击菜单中的各个子菜单时，我的菜单丢失并且系统抛出异常
更好地举例:
通过更好地解释:
我点击一个子菜单，它会将我重定向到另一个页面 在另一个页面上，我再次单击另一个子菜单，这会将我重定向到另一个页面， 等等......
我正在使用:
PrimeFaces 5.1
这是我的异常(exception):

创建的我的菜单图像:
我尝试了很多方法，但没有得到好的结果，你能帮我吗？
更新
该问题与组件 ID 有关，由于某种原因，组件正在更改 Id 以重定向页面。
请注意，我没有多次生成 MenuModel 组件一次。
我尝试使用.generateUniqueIds()方法，但仍然失败
这是我查看一个菜单的 ID 组件的日志:
首次重定向
getMenuModel = In here
getMenuModel = SIZE ELEMENTS 1
Sub Menu Name : Aceptación y Documentos > Sub Menu ID : 0 > Sub Menu ID CLIENT : 0
## Item Menu Name : Acepta Proceso > Item Menu ID : 0_0 > Item Menu ID CLIENT : 0_0
## Item Menu Name : Envio/Recepcion Documentos > Item Menu ID : 0_1 > Item Menu ID CLIENT : 0_1
第二次重定向
getMenuModel = In here
getMenuModel = SIZE ELEMENTS 1
Sub Menu Name : Aceptación y Documentos > Sub Menu ID : 0 > Sub Menu ID CLIENT : 0
## Item Menu Name : Acepta Proceso > Item Menu ID : 1 > Item Menu ID CLIENT : 1
## Item Menu Name : Envio/Recepcion Documentos > Item Menu ID : 1 > Item Menu ID CLIENT : 1
最佳答案
我设法使用菜单模型的新实例并传递已创建的每个重定向的元素来解决我的问题。
如果有人有更好的答案，请补充。因为我对这个解决方案不太满意。
private void refreshMenuModel() {
List<MenuElement> elements = this.mainMenu.getElements();
this.mainMenu = new DefaultMenuModel();
for (MenuElement menuElement : elements) {
this.mainMenu.addElement(menuElement);
}
generateUniqueIdsMenuModel();
}
private void generateUniqueIdsMenuModel() {
this.mainMenu.generateUniqueIds();
}
