Question

我将一些facelets自定义组件迁移到适当的复合组件中，但在渲染包含复合组件的视图时遇到以下错误：

在错误消息中，名称bodyId引用下面文件中的<h:body>的id，并且在创建异常消息期间对getParent()进行硬编码。 @15,26指的是下面cctest.xhtml中<composite:interface>的结尾。

以下是包含复合组件的页面：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
  "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html"
  xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:f="http://java.sun.com/jsf/core"
  xmlns:bam="http://bam.mycompany.com/jsftaglib" 
>

<f:view locale="en" id="viewId">
  <h:head id="headId">
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
    <title>Title</title>
  </h:head>
  <h:body id="bodyId">
    <bam:cctest value="hello world."/>
  </h:body>
</f:view>
</html>

这是名为cctest.xhtml的文件，它声明了复合组件cctest：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

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

  <h:head>
    <title>not used</title>
  </h:head>

  <h:body>
    <composite:interface>
      <composite:attribute name="value" required="true"/>
    </composite:interface>

    <composite:implementation>
      <h:outputText id="text_#{cc.attrs.value}" value="#{cc.attrs.value}"/>
    </composite:implementation>
  </h:body>

</html>

复合组件在名为bam.taglib.xml的文件中声明，该文件位于{WEB-INF / taglib /中，位于cctext.xhtml旁边。这是文件：

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

  <tag>
    <tag-name>cctest</tag-name>
    <source>cctest.xhtml</source>
  </tag>

</facelet-taglib>

我正在使用mojarra 2.1.21进入tomcat 7.0.41。我的faces-config.xml文件为空，没有托管bean或其他自定义组件（验证器等）。 Web.xml只声明了一些上下文参数，以及映射在* .xhtml上的faces servlet;这是上下文参数：

javax.faces.FACELETS_REFRESH_PERIOD = 1
javax.faces.FACELETS_SKIP_COMMENTS = false
javax.faces.FACELETS_LIBRARIES = /WEB-INF/taglib/bam.taglib.xml
javax.faces.PROJECT_STAGE =发展
javax.faces.VALIDATE_EMPTY_FIELDS = false
javax.faces.INTERPRET_EMPTY_STRING_SUBMITTED_VALUES_AS_NULL = true

查看facelets错误页面中显示的组件树，没有名为bodyId的元素，这可能是我的问题的提示。其副本显示如下：

<UIViewRoot id="j_id1" inView="true" locale="en" renderKitId="HTML_BASIC" rendered="true" transient="false" viewId="/pages/composite_component_test.xhtml">
  <html xmlns="http://www.w3.org/1999/xhtml">
  <UIOutput id="headId" inView="true" rendered="true" transient="false">
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/> <title>Title</title>
  </UIOutput>
</UIViewRoot>

非常感谢您提前查看此问题。
