本文记录了一次解决FreeMarker模板引擎中出现的InvalidReferenceException异常的经历。通过排查发现是因为页面中的<s:debug/> Struts标签导致的问题，删掉该标签后异常得以解决。

23:14:35,113 ERROR runtime:96 -

Expression stackObject.value.get(propertyName).toString() is undefined on line 58, column 122 in template/simple/debug.ftl.
The problematic instruction:
----------
==> ${stackObject.value.get(propertyName).toString()?html} [on line 58, column 120 in template/simple/debug.ftl]
in include "/${parameters.templateDir}/simple/debug.ftl" [on line 23, column 1 in template/xhtml/debug.ftl]
----------

Java backtrace for programmers:
----------
freemarker.core.InvalidReferenceException: Expression stackObject.value.get(propertyName).toString() is undefined on line 58, column 122 in template/simple/debug.ftl.

非常恶心的异常，搞了好半天才搞定，原来要把struts标签删掉，我的页面中有了个<s:debug/> 删掉就正常了，搞不懂！
