Answer 1

Well you cannot directly get browser-tab-close event in <a4j:ajax event="?" .../> but there is work around for this

Step1: Get tab-close event from javascript like

<h:body onunload="tabClosed();">

Step2: Make JS function and call backing bean like be

<h:form>
   <a4j:jsFunction name="tabClosed" action="#{myBean.tabIsClosed()}" ></a4j:jsFunction>
</h:form>
