I can't access your page.
I had read your code. Your page a little different with ours. You need add render attribute for "action 1" and rendered for "action 2", and "action 2" will be delete, when "action 1" response arrived. it like this: 
<a4j:commandButton id="ajaxAction1" render="action2Area"/> 
<a4j:outputPanel id="action2Area" rendered="#{!action1Click}">
 <a4j:commandButton id="ajaxAction2"/>
</a4j:outputPanel>
