分享关于Validation的错误，请大家帮忙看看
jsp页面如下：

我要对status加一个验证，validation.xml文件如下：
<form name="DeviceStatusForm">
<field property="status"
depends="required,maxlength">
<arg0 key="display.deviceaction.deviceTypeId"/>
<arg1 name="maxlength" key="${var:maxlength}" resource="false"/>
<var>
<var-name>maxlength</var-name>
<var-value>4</var-value>
</var>
</field>
</form>
struts-config.xml文件如下：
<action path="/deviceStatusAction"
type="sc.snow.devicestatus.DeviceStatusAction"
name="DeviceStatusForm"
scope="request"
validate="true"
parameter="dispatch"
input="/pages/devicestatus/deviceStatusForm.jsp"
>
<forward
name="continue"
path="/pages/devicestatus/deviceStatusResult.jsp"/>
</action>
错误信息是：
