Primefaces：多次选择p：dataTable中的同一行

Question

I have a simple p:dataTable which fires an AJAX event when selecting a row:

<p:dataTable var="c" value="#{myBean.dmCars}"
             selection="#{myBean.car}" selectionMode="single">
  <p:ajax event="rowSelect" listener="#{myBean.select}"/>
  <p:column>  
    <f:facet name="header">Name</f:facet>  
      <h:outputText value="#{c.name}"/>  
  </p:column>
</p:dataTable>

This works fine, but I can only select a row once. I want to select the same row multiple times and the event listener of p:ajax invoked for each click.

Update I think it's because the row has somewhere the state selected . You see the selected row with a grey background in this example: http://www.primefaces.org/showcase/ui/datatableRowSelectionInstant.jsf

@Daniel and @MattHandy, thank you both for your support. I found a solution to this issue:

public void select()
{
  // Do some stuff
  car=null;
}

In the backing bean i set the value holder to null after I've processed the event.
