Hello,
I will have access to other DAO instances within a DAO instance to have access to other data infos. Therefore I need the context id of current DAO instance.
For example:
I have a UserSqlMapDao and a GroupSqlMapDao.
I support requesting users with group infos. Therefore I will request all groups from the GroupSqlMapDao within the UserSqlMapDao class.
I support also more than one database so I need the context id.
Best regards
Manuel

What is it that you are trying to accomplish with this?
