使用logic:iterate遇到的问题

王朝java/jsp·作者佚名 2006-01-10

<logic:iterate id="agUser" name="agUserOverview">

<tr>

<td align="left" class="page"

<bean:write name="agUser" property="userid" filter="true" /></a>

</td>

<logic:equal name="agUser" property="roleid" value="1">

管理员

</logic:equal>

<logic:equal name="agUser" property="roleid" value="2">

普通员工

</logic:equal>

</td>

</tr>

</logic:iterate>

如果把红色那段去掉，程序就能运行，也能把数据表现出来，但是如果留下这段，页面就会出错误：
