看不明白，在那里自增了？

可以详细介绍一下，a4j:commandLink在richfaces中richtable中应用。

我的代码是： <a4j:commandLink id="idyflagk" value="#{sysstatus.failureCnt}"
action="#{SysIntegStatCountBean.getFailureCntStatus}"
reRender="dataGrid1,dxCauseTemplateSetDiv" immediate="true">
  <a4j:actionparam name="thirdHost" value="#{sysstatus.thirdHost}"></a4j:actionparam>  
</a4j:commandLink>

但是链接根本不起作用。getFailureCntStatus是bean中的方法dataGrid1,dxCauseTemplateSetDiv是渲染的区域thirdHost是参数。
