在Freemarker引用eXtremeComponents?

相同的环境，jsp可以，Freemarker报错
我的代码是：
<@ec.table items="moduleList" action="listModule.do"
imagePath="../styles/system/<@bean.message
key='SYSTEM.CSS'/>/eXtremeComponents/images/*.gif">
        <@ec.row>
                <@ec.column property="id"/>
                <@ec.column property="name"/>
                <@ec.column property="url"/>
        </...@ec.row>
</...@ec.table>
报错：
FreeMarker template error!

on line 18, column 9 in system/listModule.ftl ec.row not found.
The problematic instruction:
----------
==> user-directive ec.row [on line 18, column 9 in
system/listModule.ftl]
 in user-directive ec.table [on line 17, column 1 in
system/listModule.ftl]

Java backtrace for programmers:

谁知道是什么原因？

listModule.ftl是不是这个文件的事情呀，你看看？
