包路径：javax.faces.webapp.UIComponentClassicTagBase
类名称：UIComponentClassicTagBase
方法名：isDuplicateId
UIComponentClassicTagBase.isDuplicateId介绍
[英]Returns true if a component already exists with the same id. This will be the case if this tag is nested within tag or any other JSTL loop tag or if the page has components with the same `Id`. [中]如果已存在具有相同`id`的组件，则返回true。如果此标记嵌套在标记或任何其他JSTL循环标记中，或者如果页面具有具有相同Id的组件，则会出现这种情况。
