  <pre><code>&lt;h:form id="form"&gt;
  
  
  
  
         &lt;p:dataTable id="cars" var="car" value="#{articleinbean.listefour()}" rowKey="#{car.idfourlivr}"  
                   selection="#{articleinbean.selectedfourlivr}" selectionMode="single" &gt;  
  
  
                    &lt;p:ajax event="rowSelect"  oncomplete="carDialog.show()"  listener="#{familleBean.onRowSelect}" /&gt;  
  
          &lt;f:facet name="header"&gt;  
             Liste des articles 
          &lt;/f:facet&gt; 
           &lt;p:column headerText="Numero de fournisseur" &gt;  
              #{car.idfourlivr}  
          &lt;/p:column&gt;  
  
          &lt;p:column headerText="Nom de fournisseur"&gt;  
              #{car.nomfourlivr}  
          &lt;/p:column&gt;    
     &lt;/p:dataTable&gt;  
  
  
  
       &lt;/h:form&gt;
