JSF2:ui:include:组件ID必须是唯一的

Question

基本问题:

包含一个页面,其中包含具有组件ID的组件,多次无法完成.但是,我如何能够在包含页面的情况下引用该组件？

例:

included.xhtml

....
<h:form id="foo"/>
....
<!-- here i need reference to foo component of this page -->

的index.xhtml

....
<ui:include src="included.xhtml" />
<ui:include src="included.xhtml" />
<ui:include src="included.xhtml" />

Answer 1

随着ui:includeid将被复制.

您可以将参数传递给包含的xhtml并为您的ID添加前缀

<ui:include src="included.xhtml">
    <ui:param name="idPrefix" value="myFormIdPrefix"/>
</ui:include>

在包含的xhtml中

<h:form id="#{idPrefix}_foo"/>

现在可以将id引用为 #{idPrefix}_foo
