代码里是这样写的
SalPlan plan=this.PlanService.findPlanById(id);
request.setAttribute("planByid", plan);页面时
<logic:iterate id="item" name="planByid" type="com.accp.crm.entity.SalPlan"> 
<tr>
<td class="list_data_text"><bean:write name="item" property="plaDate" format="yyyy年MM月dd日" />&nbsp;</td>
</tr>
</logic:iterate>运行时会报Cannot find bean: "planByid" in any scope错误
应该怎样改
