Question

我想使用模型文件渲染嵌套的2级导航。导航可以改变。

有一个Simple Bean NavigationItem，它包含标题，目标，图标和可能的子项列表。

导航创建非常简单：

<ui:composition xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://xmlns.jcp.org/jsf/facelets" xmlns:h="http://xmlns.jcp.org/jsf/html" xmlns:f="http://xmlns.jcp.org/jsf/core" xmlns:b="http://butterfaces.org/components" >

    <ul id="side-nav" class="main-menu navbar-collapse collapse">

        <b:repeat value="#{navigation.values}" var="nav" rendered="true">
            <li class="#{nav.hasSubItems()==false ? '' : 'has-sub'}">
                <h:link outcome="#{nav.target}">
                    <i class="#{nav.icon}"></i>
                    <span class="title">#{nav.title}</span>
                </h:link>

                <ui:fragment rendered="#{nav.hasSubItems()}">
                    <ul class="nav collapse">
                        <b:repeat value="#{nav.subItems}" var="subNav" rendered="true">
                            <li>
                                <h:link outcome="#{subNav.target}">
                                    <span class="title">#{subNav.title}</span>
                                </h:link>
                            </li>
                        </b:repeat>
                    </ul>
                </ui:fragment>

            </li>
        </b:repeat>
    </ul>

</ui:composition>

这是我的JSF

        process.nextTick(function() { throw err; })
                                      ^

    at WritableState.onwrite (_stream_writable.js:89:5)
    at fireErrorCallbacks (net.js:442:13)

我的预期结果：

甲
- 1
- 2
- 3
乙
- 4
- 5
Ç
- 6
d

我的实际结果是：

甲
- 1
- 2
- 3
乙
- 1
- 2
- 3
Ç
- 1
- 2
- 3
d

我有什么想念或错吗？我在Tomcat 8上使用Mojarra 2.2.8

Answer 1

mojarra repeat组件存在一些严重问题，因此我们在butterfaces中创建了自己的组件（如primefaces，richfaces等）。

这似乎是一个错误，我创建了一个问题：https://github.com/ButterFaces/ButterFaces/issues/63

嵌套b：重复 - 第二次重复始终相同
