Ajax脚本在IE中不起作用

I am using JSF 1,2 and I found that IE9 or higher doesn't support Ajax scripts and requests. In my project I have the same problems and errors as u can reproduce on: this source using IE 9+

<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:a4j="http://richfaces.org/a4j"
xmlns:rich="http://richfaces.org/rich">
<h:form>
    <rich:panel bodyClass="rich-laguna-panel-no-header">
        <a4j:commandButton value="Set Name to Alex"  reRender="rep" >
            <a4j:actionparam name="username" value="Alex" assignTo="#{userBean.name}"/>
        </a4j:commandButton>
        <rich:spacer width="20" />
        <a4j:commandButton value="Set Name to John"  reRender="rep" >
            <a4j:actionparam name="username" value="John" assignTo="#{userBean.name}"/>
        </a4j:commandButton>
    </rich:panel>
    <rich:spacer height="1" />
    <rich:panel bodyClass="rich-laguna-panel-no-header">
        <h:outputText id="rep" value="Selected Name:#{userBean.name}"/>
    </rich:panel>
</h:form>

Has someone ever faced with this problem and found any solution?

The problem should be fixed on server and not on user environment.

Thank you.

RichFaces 3.x does not support IE9. Refer to this answer for more details.

Possible solutions (as stated in the referenced answer):

1. Upgrade to RichFaces 4.
2. Turn on or force IE8 compatibility mode
3. Patch RichFaces 3 (mostly javascripts) to make it work with IE9 in native mode (refer to the JBoss forum topic from the referenced answer for more details).

It works in IE 9+ with IE8 compatibility mode. Add meta tag <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" /> and try it.
