Freemarker网站在IE10中抛出错误[关闭]

Question

当我在 IE10 桌面打开 this website 时，它显示 Freemarker 错误堆栈。

Error: on line 18, column 32 in WEB-INF/ftl/common/requestVariables.ftl
Expecting a number here, found: .
The problematic instruction:
----------
==> browserMinor=applicationBean.browser.browserMinor?number [on line 18, column 17 in WEB-INF/ftl/common/requestVariables.ftl]
 in include "/WEB-INF/ftl/common/requestVariables.ftl" [on line 12, column 1 in WEB-INF/ftl/login/login.ftl]
----------

Java backtrace for programmers:
----------

如果我更改连接字符串(F12 developer tools, press Tools > Change user-agen string > Mozilla Firefox)，它会正常工作。

是因为框架中的浏览器嗅探吗？

Answer 1

似乎 Web 应用程序框架（不是 FreeMarker）为 IE10 将 browserMinor 设置为 ""，这当然不是一个数字。要么在此处输入“0”，要么必须修改 requestVariables.ftl 以处理这种情况。
