<我的:foo>标签库支持命名空间:http://java.sun.com/jsf/composite/mycomponents，但没有为名称定义标签:foo [英] <my:foo> Tag Library supports namespace: http://java.sun.com/jsf/composite/mycomponents, but no tag was defined for name: foo
问题描述
我有一个名为
I have a composite component named <my:foo> and I'm building another composite component named <my:bar>. But when I attempt to use <my:foo> inside the <cc:implementation> of <my:bar>, the following exception is been thrown:
<my:foo> 标签库支持命名空间:http://java.sun.com/jsf/composite/mycomponents，但没有为名称定义标签:foo
<my:foo>Tag Library supports namespace: http://java.sun.com/jsf/composite/mycomponents, but no tag was defined for name: foo
这是怎么引起的，我该如何解决?
How is this caused and how can I solve it?
推荐答案
这是由在 Mojarra 2.1.8 中引入、在 2.1.9 中继续并在 2.1.10 中修复的错误引起的.此错误导致无法在根 XML 元素中声明复合组件自己的 XML 命名空间，例如 <;html>/etc 如下:
This is caused by a bug which was introduced in Mojarra 2.1.8, continued in 2.1.9 and is fixed in 2.1.10. This bug causes that composite component's own XML namespace cannot be declared in a root XML element like <ui:component>/<ui:composition>/<html>/etc as follows:
<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"
xmlns:my="http://java.sun.com/jsf/composite/mycomponents"
>
<cc:interface>
...
</cc:interface>
<cc:implementation>
<my:foo />
</cc:implementation>
</ui:component>
当您尝试将
This would result in the following exception when you attempt to nest <my:foo> inside the <cc:implementation>.
<my:foo> 标签库支持命名空间:http://java.sun.com/jsf/composite/mycomponents，但没有为名称定义标签:foo
<my:foo>Tag Library supports namespace: http://java.sun.com/jsf/composite/mycomponents, but no tag was defined for name: foo
目前的解决方法，除了降级到 2.1.7 并等待 2.1.10 发布之外，是将 XML 命名空间声明移到
The current workaround, apart from downgrading to 2.1.7 and waiting for 2.1.10 to be released, is to move the XML namespace declaration into the <cc:implementation>.
<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 xmlns:my="http://java.sun.com/jsf/composite/mycomponents">
<my:foo />
</cc:implementation>
</ui:component>
