为什么复合组件内构面内的commandLink会出现错误？

Leo*_*amp 5 jsf facet commandlink composite-component mojarra

当我创建一个包含构面的复合组件并将命令链接放置在该构面中时，出现错误消息： This link is disabled as it is not nested within a JSF form.

commandButton的行为方式不同，所以我倾向于这是一个错误。

这是我的浏览器的功能：

关于我可能做错了什么的任何想法，或者这确实是Mojarra 2.2.7中的错误？（与NetBeans 8.0.2捆绑在一起）

an old thread but i think the current behaviour is a bug, because the following works, and so it should work in a composite component:

component.xhtml:

<?xml version='1.0' encoding='UTF-8' ?>
<ui:component
xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://xmlns.jcp.org/jsf/html"
xmlns:cc="http://xmlns.jcp.org/jsf/composite"
xmlns:f="http://xmlns.jcp.org/jsf/core"
xmlns:a="http://xmlns.jcp.org/jsf/passthrough"
xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
>
<cc:interface>
    <cc:facet name="someFacet" required="true"/>
</cc:interface>
<cc:implementation>
    <h:commandLink value="this link should not work (not in a form)"/><br/>
        <h:commandLink value="this link works as expected (within form, but not in facet)"/><br/>
        <cc:renderFacet name="someFacet"/>
</cc:implementation>
</ui:component>

Using it (index.xhtml):

<?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">

      xmlns:f="http://xmlns.jcp.org/jsf/core">
    <h:head>
    </h:head>
    <h:body>
     <h:form>
        <mycomp:component>
            <f:facet name="someFacet">
                <h:commandLink value="this link should work, but does not (within form, within facet)"/><br/>
                <h:commandButton value="this button works as expected (within form, within facet)"/><br/>

Also the generated HTML output in both cases generates the button in the right place in the component tree (under the form). But the clientId generated for the button, differs in both cases:

First thread post --> clientId without form ID
My post --> clientId includes form ID

In my opinion this seems to be a bug, but perhaps someone can convince me that it is not ;D

Using Mojarra 2.2.13 (Primefaces 6.x).
