Sorry for the cross post, I 've already submit those code samples in the Richfaces users forum but no answer.... :(

I think jiras should be created for it but i have a read-only access to RC's jira.

1)
With RC 3.2.1 (and also 3.2.2b5), the following code has a very strange behavior on IE. the onClick event on one of the checkbox makes a javascript error occurs and the cell "value" disappears !!

<rich:dataTable value="#{testBean.listModel}" var="row">
 <rich:column id="value" styleClass="#{row.updated ? 'updated':'NotUpdated'}">
 <h:outputText value="#{row.value}" />
 </rich:column>
 <rich:column>
 <h:selectBooleanCheckbox id="check" value="#{row.value}">
 <a4j:support event="onclick" ajaxSingle="true" action="#{testBean.onClickUpdateValue}" reRender="value"/>
 </h:selectBooleanCheckbox>
 </rich:column>
</rich:dataTable>

<rich:tabPanel
 id="tabPanel"
 switchType="ajax"
 selectedTab="#{testhandler.tab}">

 <rich:tab id="foo" label="foo tab"
 ajaxSingle="true">
 <h:outputText value="Foo" />
 </rich:tab>
 <rich:tab id="bar" label="bar tab"
 ajaxSingle="true">
 <h:outputText value="bar"/>
 </rich:tab>
 </rich:tabPanel>
