displaytag标签无法翻页

dsf6gf 2007-06-22 02:56:14

这是那段代码
<display:table name="show" style="mars" pagesize="20">
<display:column property="mid" title="编号" class="idcol"/>
<display:column property="mname" />
<display:column property="geshou" class="tableCellError"/>

</display:table>
如果不分页都显示，当分页后只显示第一页，点击下一也就报错...
500错误为：
description The server encountered an internal error () that prevented it from fulfilling this request.
