在JSF 2中是否可以将模板与复合组件一起使用?

问题描述

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
    ...
    template="inputLayout.xhtml">

    <composite:interface>
        <composite:attribute name="name" />
        <composite:attribute name="value" />
    </composite:interface>

    <composite:implementation>
      <!-- <ui:define name="content"> -->
          <h:message for="textPanel" style="color:red;" />
          #{cc.attrs.name} :
          <h:inputText id="name" value="#{cc.attrs.value}" />
      <!-- <ui:define> -->
    </composite:implementation>
</ui:composition>

问题在于，即使 ui:define 也已注释了呈现的内容.因此，就像 ui:define 被忽略了，还是我错过了一些东西?谢谢.

The problem is that even the ui:define is commented the content is rendered.So it is like the ui:define is ignored or Am I missing some thing ?Thanks.

推荐答案

这确实不起作用.在实现内部，您需要 <ui:decorate> .

This will indeed not work. You need <ui:decorate> inside the implementation instead.

<ui:component
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:cc="http://java.sun.com/jsf/composite"
>
    <cc:interface>
        ...
    </cc:interface>
    <cc:implementation>
        <ui:decorate template="/WEB-INF/inputLayout.xhtml">
            <ui:define name="content">
                ...
            </ui:define>
        </ui:decorate>
    </cc:implementation>
</ui:component>
