p：commandLink in p：dataTable只有第一页有效

Question

我在这里做错了什么？ 第一页没有问题。当我在第一页中点击带有“p：commandlink”的超链接时。这非常有效。当我点击下一页时，我的对话窗口中没有任何结果。 我已将SessionScoped更改为ViewScoped，但所有内容都相同，只有第一页的超链接才有效。

我使用： Primefaces 4.0

        <p:dataTable id="mycontent" 
                     value="#{outputBean.lazyModel}" 
                     var="item"
                     paginator="true" rows="10" 
                     paginatorTemplate="  {PageLinks} "  
                     rowsPerPageTemplate="5,10,15"
                     lazy="true">  


            <p:column>
               <p:commandLink  value="#{item.name} #{item.model}" 
                               process="@this" update=":workform:myDialog" 
                               oncomplete="dialogcontent.show();" >
                    <f:setPropertyActionListener value="#{item}" target="#{outputBean.data}" />  
                </p:commandLink>
            </p:column>

        </p:dataTable>
