Question

当我在IE10桌面上打开this website时，会显示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)，则效果很好。

是否是由于框架中的浏览器嗅探？

Answer 1

似乎Web应用程序框架（不是FreeMarker）为IE10设置了browserMinor到""，这当然不是一个数字。它应该在这里放“0”，或者必须修改requestVariables.ftl来处理这种情况。
