刚开始使用jsf，请教跳转问题，谢谢各位
下面是我遇到的问题
<managed-bean>
    <managed-bean-name> custorderDAOImpl </managed-bean-name>
    <managed-bean-class> com.cheers.jzth.custorder.CustOrderDAOImpl </managed-bean-class>

一开始是一个订单列表，点“详细”可以看到订单的详情，实现如下
<h:commandLink   value= "detail "   action= "#{custorderDAOImpl.detail} "   >
      <f:param   value= "#{order.id} "   name= "orderid "   />
</h:commandLink>

String   detail()
{
      ..   取得订单详细列表，
    return   "detail "
}
这一步没有问题，然后是在详细列表中有一个“修改”按钮
<h:commandLink   value= "edit1 "  
    action= "#{custorderinfDAOImpl.editorderinfo} "   >
        <f:param   value= "#{order.comp_id.orderid} "   name= "orderid "   />
        <f:param   value= "#{order.comp_id.merchid} "   name= "merchid "   /> <
