Concurrent call to conversation on orderingList

How can I prevent the "503 Concurrent call to conversation" error when the user done fast clicks to reorder the orderingList?

Is the new rich:queue the solution?

My view:

<rich:orderingList valueChangeListener="#{perguntasAction.ordenarPerguntas}" value="#{perguntasAction.perguntas}" var="_pergunta">
 <s:convertEntity/>
 <rich:column>
 <f:facet name="header">Title</f:facet>
 <h:outputText value="#{_pergunta.titulo}" />
 </rich:column>
 <a4j:support event="onorderchanged" limitToList="true" ajaxSingle="true"/>
</rich:orderingList>

My bean is in Seam's conversation scope.

a4j:queue is a new component introduced in 3.3.0.GA. It was designed as an improvement for already existing prior to 3.3.0.GA queues feature.
