打开表单，提示null错误

版本 sp6，在打开表单的时候，提示 null 错误，不知道什么原因。再次贴出 tomcat 中的 错误信息，方便看看吗？不知道有没有简单的办法，通过修改数据库中的信息来解决。

您好:针对您这个问题麻烦按照帖子：http://www.teemlink.com/bbs/view ... 26amp%3Btypeid%3D12 中的第八楼进行尝试。
只能先让您把数据恢复到最初始的状态。

通过那样的方法，没有找到相关记录。

您好：动态表单中的state字段值保存的是流程实例id，昨天您说这个字段值是空的，那麻烦您通过sql语句查询下这个流程实例在T_FLOWSTATERT表中是什么，类似sql语句如下：
select a.*,b.id from TLK_主流程表单 a,T_FLOWSTATERT b where a.ID=b.DOCID
动态表单中的id值和T_FLOWSTATERT的docid值一样，而动态表单中的state值就是T_FLOWSTATERT表中id的字段值。 既然您只有这条记录打开为null，那您可以根据这条记录的id值查询看看。

这个 我 现在修改了，再能帮我 看看 动态表单中的字段 LASTFLOWOPERATION 的值 只有80 和 81 吗？如果出现 7 和 1 是什么意思？谢谢

您好，您可以参考一下该帖子，流程参数具体代表什么：http://www.teemlink.com/bbs/view ... hlight=%C1%F7%B3%CC

目前 已经修改合适了，看看流程 流转的时候，在出现新问题不，谢谢，这个帖子可以结贴了
