1、被bs表单引用的app表单，不能勾选"**是否下拉刷新**"单选框，否则bs页面打开时会直接报错  2、执行下面的语句，返回的结果集中 refreshflg、pagesize 字段值不能为 null，不然会导致嵌入失败 ``` select formno, formstyle,refreshflg,pagesize,serverno,formname,condition,hascondition,isnull(headerstates,1) as headerstates,isnull(footerstates,1) as footerstates,isnull(pagerank,0) as pagerank,isnull(gobackrefresh,1) as gobackrefresh from xt_appform c where c.formid='chart12' and c.appno='oa' ```
