Hello!
I have 2E layout. In the left i have a Tree with names of users groups, in the rigth i have a grid with users, which load users of chosen group. When I try, for example, add user to group with id = 1 at first time user add to the group and the row appeared in the DB, then i delete this user. DataProcessor work correctly. But when i try to add the same user again to the same group, the new row remains bold and row doesn’t appear in the DB. What can I do in this situation?
