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

<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.
