JAR 中的复合组件与 cc.attrs 相关

Question

对于打包在 JAR 中的复合组件，我使用了 和简单的 ，当然还有 ><抄送：实现>。

在开发阶段，我有一个 javax.faces.view.facelets.TagException ，它抱怨 cc:interface 组件未检测到标识符“j_idt6.getParent()”。在生产阶段，它似乎可以工作，但是 的值没有按预期显示。

我在网上看到了一个JIRA问题JAVASERVERFACES-1903，但看起来有点老的。有人知道如何解决它吗？您认为这个问题有一天会得到解决吗？您如何在项目中处理 JAR 文件中的复合组件？

我的配置是 Glassfish 3.1 下的 Mojarra 2.1.4。

来自OP帖子的更新，如下：

这是错误：

我的JAR中的文件：

META-INF/resources/components/sampleOutput.xhtml

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:cc="http://java.sun.com/jsf/composite">

    <!-- INTERFACE -->
    <cc:interface>
        <cc:attribute name="colorRed" default="F00" />
    </cc:interface>

    <!-- IMPLEMENTATION -->
    <cc:implementation>
        <h:panelGroup layout="block" styleClass="componentContainer" style="border:1px solid \##{cc.attrs.colorRed};">
            <h:outputText value="Sample Output Component #{cc.attrs.colorRed}" />
        </h:panelGroup>
    </cc:implementation>

</html>

和META-INF/components.taglib。 XML

<facelet-taglib xmlns="http://java.sun.com/xml/ns/javaee"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</facelet-taglib>

Answer 1

您根本不需要 taglib.xml 文件。删除它并通过以下命名空间在视图中引用您的组合：

xmlns:ec="http://java.sun.com/jsf/composite/components"

“/components”部分引用资源文件夹中的文件夹“/components”。

另请参阅：

• 我们的复合组件 wiki 页面
• 具有共享代码的多个 JSF 项目的结构

Answer 2

好的解决了。错误出现在命名空间中，并且使用 cc:xxx 而不是 composite:xxx

    <?xml version="1.0"?>
    <facelet-taglib xmlns="http://java.sun.com/xml/ns/javaee"
                  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                  xmlns:composite="http://java.sun.com/jsf/composite"
                  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facelettaglibrary_2_0.xsd"
                  version="2.0">

        <namespace>http://java.sun.com/jsf/composite</namespace>

        <tag>
            <tag-name>sampleExternalComponent</tag-name>
            <source>resources/ec/sampleExternalComponent.xhtml</source>
        </tag>

    </facelet-taglib>

组件：

<?xml version='1.0' encoding='UTF-8' ?>
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:composite="http://java.sun.com/jsf/composite"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:ui="http://java.sun.com/jsf/facelets">

    <ui:composition>
        <!-- INTERFACE -->
        <composite:interface>
            <composite:attribute name="color" default="000000" required="false" />
        </composite:interface>

        <!-- IMPLEMENTATION -->
        <composite:implementation>
            <h:outputText value="#{sampleExternalComponentBean} || #{sampleExternalComponentBean.name} || #{cc.id} || #{cc.attrs.color}" style="color: \##{cc.attrs.color};" />
        </composite:implementation>
    </ui:composition>
</html>

并在 WAR 中调用它： xmlns:ec="http://java.sun.com/jsf/composite/ec"< /code> 和
