raw input-fields in h:form breaks JSF-Application

I have updated from JBOSS AS 7.1.0 FINAL to JBOSS AS 7.1.1 FINAL and after that a problem with its underlying JSF-Implementation occured.

The following two versions shows the problem:

When clicking the button 'my-btn' of VERSION 1,
then JSF do not send any data to the server.
It even does not say anything in my log or my facelets-debug-page. The error is totally silent!

However, using VERSION 1 with JBOSS AS 7.1.0 FINAL works without error !!

VERSION 2 does work both in JBOSS AS 7.1.0 FINAL and JBOSS AS 7.1.1 FINAL.
When clicking the button 'my-btn' of VERSION 2,
then JSF sends data to the server,
because I placed my input-field outside of the JSF-Form-Tag.
The input-field is NOT a JSF-component, I use it only for client-side-purpose (so no need for h:inputText).
Why I am forced to use a h:inputText, when not wanting it ?

VERSION 1:

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:a4j="http://richfaces.org/a4j">

<h:form id="overall-form" prependId="false">

<header id="my-hd">
<h:commandLink id="my-btn" value="get data " action="#

{myBean.getData}">
<f:ajax render="@form" />
</h:commandLink>
</header>

<!-- I use a raw html-input-field only for client-side-purpose, so I do not want to use a <h:inputText /> , but this input-field breaks my JSF-Application !->
<div
<input type="text" value=""/>
</div>


</h:form>

VERSION 2:

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:a4j="http://richfaces.org/a4j">


<h:form id="overall-form" prependId="false">
<header id="my-hd">
<h:commandLink id="my-btn" value="get data " action="#{myBean.getData}

">
<f:ajax render="@form" />
</h:commandLink>
</header>
</h:form>

<!-- I use a raw html-input-field only for client-side-purpose, so I do not want to use a <h:inputText /> , as it is no more included within a JSF-form-tag, my JSF-Application works without errors->
<div
<input type="text" value=""/>
</div>

I guess, it is a bug in JSF-lib which was upgraded in JBOSS AS 7.1.1 FINAL to JSF 2.1.7.
