【中文标题】JSF 2 动态用户界面：包括从 2.1.7 到 2.1.9 不工作

【英文标题】：JSF 2 dynamic ui:include not working from 2.1.7 to 2.1.9

【发布时间】：2012-10-18 17:49:27

【问题描述】：

我有一个 JSF 2/CDI webapp，它可以动态配置一些特定的管理页面。它使用一个 bean 来决定要包含哪个页面：

<ui:include src="#myBean.myDynamicPath"/>

为了使其正常工作，我已将使用它的页面添加到 javax.faces.FULL_STATE_SAVING_VIEW_IDS 上下文参数中，并且在将 JSF 库从 2.1.7 更新到 2.1 之前，一切正常。 9（和最新的有同样的问题）。

当我尝试在页面上执行某些操作时，我得到一个很长的异常：

ui:include 的工作方式是否发生了变化？有人有什么想法让它再次工作吗？我需要更新 JSF 库。

【问题讨论】：

能否贴出渲染组件“tabs:imagesListForm:imagesListDG:j_idt55”的相关代码？

你好@Ravi，我放哪个代码都没关系，无论如何它都不起作用，在这种情况下，它是一个 p:dataTable 里面的一个 h:form 里面的一个 p:tab 里面的一个 p:tabView但我也尝试过添加简单的组件，结果是一样的......

@Ravi 不，我已经检查过所有的 id 都是唯一的......如果我使用 JSF 2.1.7 它也可以正常工作......

【参考方案1】：

快速解决方法：尝试说明所有元素的 ID 值。并确保 ID 是唯一的。

您可以检查生成的 html 中生成的 ID，以确定导致问题的标签。
