在ui:repeat中,组件具有相同的id。

不幸的是,如果您尝试动态创建选项卡,则primefaces手风琴面板在2.2.1版本中的表现不佳。这是我的情况,如果用户单击添加图标,则需要创建手风琴,并在单击x图标时删除。没问题,我已经创建了自己的组合组件,如下所示:

<c:interface>
    <c:attribute name="titulo" default="" required="false" />
    <c:attribute name="renderizar" default="true" required="false" />
    <c:attribute name="width" required="false" default="300"/>
    <c:facet name="extra" required="false" />
</c:interface>

<c:implementation>
    <h:outputStylesheet library="css" name="hrgiAccordion.css" target="head" />
    <h:outputStylesheet library="css" name="clearfix.css" target="head" />
    <h:outputScript library="js" name="hrgiAccordion.js" target="head" />
    <h:panelGroup layout="block" rendered="#{cc.attrs.renderizar}"
    styleClass="hrgi-accordion clearfix" style="width: #{cc.attrs.width}px;">
        <div class="hrgi-cabecalho-accordion clearfix"
            onclick="abrirAccordion(this)">
            <h:outputLabel value="#{cc.attrs.titulo}" />
            <c:renderFacet name="extra" required="false"/>
        </div>
        <h:panelGroup layout="block" class="hrgi-conteudo-accordion clearfix">
            <c:insertChildren />
        </h:panelGroup>
    </h:panelGroup>
</c:implementation>

它可以正常工作,但我有一些特殊的需求......手风琴标签页的内容是一些选择和一个动态表格,其中包含一个inputField和一个spinner(由我创建),您可以在这里看到用户界面:
当用户在spinners中插入值时,“Total das parcelas”标签应更新,但仅当对话框只有一个手风琴选项卡时才会更新!查看生成的HTML代码,我发现不同手风琴选项卡中的spinners是相等的!这可能是我无法更新值的原因。这是此对话框的代码:

在这张图片中,你可以看到发生了什么,PrimeFaces datatable中的组件ID没有附加上ui:repeat的索引:

html inspector

我该如何解决这个问题?

这是一个Mojarra bug,当你将一个UIData组件嵌套在UIRepeat中时会出现。我曾经报告过它作为问题1830。到目前为止它还没有被修复,在MyFaces中可以正常工作。在Mojarra中,UIRepeat有很多问题,但在MyFaces中完美运行。
如果你想/需要继续使用Mojarra,因此不能用MyFaces替换它,请考虑用一个基于UIData的完整组件来替换UIRepeat。例如,Tomahawk的<t:dataList>不会生成任何额外的标记,并且是一个很好的<ui:repeat>替代品。或者你可以使用PrimeFaces的<p:dataList>并用一些CSS list-style-type: none隐藏列表项目符号。
更新:报告的问题在Mojarra 2.1.12和2.2.0-m06中已经修复。因此,如果可以,请升级至至少该版本。

没有什么是完美的,但MyFaces开发团队在处理错误报告方面做得很好。MyFaces主要开发人员在SO上也非常活跃。 - BalusC
