我已将我的primefaces版本更新为4.0RC1，因为它支持JSF 2.2。 （Over Glassfish 4）
我使用primefaces菜单栏来显示我的应用程序菜单，它曾经在primefaces 3.5中正常工作但它不再起作用了。
<p:menubar model="#{myBean.userMenu}" />
正如您在上面的代码中看到的那样，我使用模型以编程方式显示我的菜单。
尝试渲染视图时，抛出以下异常：

答案 0 :(得分：2)
我已经解决了我的问题，现在将org.primefaces.model.menu.BaseMenuModel子类化为这样：
public class MyDefaultMenuModel extends BaseMenuModel {
private boolean generated = false;
@Override
public void generateUniqueIds() {
if(!generated) {
generateUniqueIds(getElements(), "_");
generated = true;
}
}
private void generateUniqueIds(List<MenuElement> elements, String seed) {
if(elements == null || elements.isEmpty()) {
return;
}
int counter = 0;
for(MenuElement element : elements) {
String id = (seed == null) ? String.valueOf(counter++) : seed + "_" + counter++;
element.setId(id);
if(element instanceof MenuGroup) {
generateUniqueIds(((MenuGroup) element).getElements(), id);
}
}
}
}
id验证不允许以数字开头的ID
我已经解决了与问题Issue 6187
