最近用jfinal修改框架,不小心删除了某些东西,导致整个项目分页不可用了

有没有人知道这是什么原因,急!,报下面的错,但是感觉和前端写的没关系,是后端删了某些代码导致的,找不到原因,有没有帮助一下的!

Caused by: freemarker.core.InvalidReferenceException: The following has evaluated to null or missing:

Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use [#if myOptionalVar??]when-present[#else]when-missing[/#if]. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??

看起来是跟模板相关的东西，你是修改框架自带的包了吗

page.pageNumbe
没有这个参数的值，检查下代码确认有没有page对象以及相关属性

WEB-INF/admin/hzsc/list.html 这个资源line 140报错呀，目测是myOptionalVar 这个变量为null，好好检查下吧！

模板list.html140行代码有问题，你确认下哪个变量是不是赋值有问题

The following has evaluated to null or missing:
==> pagination [in template "WEB-INF/admin/hzsc/list.html" at line 140, column 31]
list 页面140行解析变量时有空值null导致报错。
