记一个bean:write的问题(struts1.3.10)

<logic:iterate id="departmentform" name="departList" >
<tr>
<td><bean:write name="departmentform" property="id" />
<%
//=departmentform.getId()
%></td>
<td><bean:write name="departmentform" property="name"/></td>
<td><bean:write name="departmentform" property="description"/></td>


这个<bean:write name="departmentform" property="id" />怎么都取不到,其它两个都能显示.换成表达式也可以显示,页面显示错误

问题刚刚解决,这是个非常难以理解的答案,一定要在应用中添加资源文件!
我的困惑在于:
为什么不加资源文件的时候<bean:write name="departmentform" property="name"/>都能正常显示,
就是<bean:write name="departmentform" property="id"/>不能?

另外换用JSTL<c:out.....>实现,则这种取属性的必须版本为JSTL1.1以上.
