报错信息如下：

10:06:39:表达式值为空(NULL):p.items 位于64行 资源:/views/htmltags/form/select.html
61|
========================
调用栈:
/views/htmltags/form/select.html 行：64
/views/modules/seller/sellerList.html 行：57
] with root cause
org.beetl.core.exception.BeetlException: null
at org.beetl.core.statement.ForStatement.execute(ForStatement.java:83)

1、什么原因导致了以上报错
2、 /views/htmltags/form此文件夹在哪个地方，我的项目中views下只有modules一个文件夹

谢谢！
