Note: (Used English can be faulty, I use a translator.)

I use a view that recovers me the registrations of a table that has an index
candidate that unites three fields; and it recovers the data on the base of two
conditions, which you leave like it continues:

SELEC Fields FROM Table WHERE Field1 = ?cC1 AND Field2 = ?cC2

Then use a form where the user can publish the registrations on a control grid.
The problem is that when I use Buffering=3 (Optimist for lines) when adding
registrations, it happens the error #1884 ' the unicidad of the índice' has
been violated, although I generate the code automatically and when running the
one it traces everything it is unchained correctly; and when I use Buffering=5
(Optimist for tables) after adding 2 registrations, to the third registration
that I add, it causes that the immediately previous one disappears of the grid.

Luego uso un formulario en donde el usuario pueda editar los registros sobre un

al agregar registros, ocurre el error #1884 'Se ha violado la unicidad del
índice', aunque genero el código automáticamente y al correr el trace todo se
desencadena correctamente; y cuando uso Buffering=5 (Optimista por tablas)
después de agregar 2 registros, al tercer registro que agrego, causa que el
inmediatamente anterior desaparezca del grid.


Si tienen alguna sugerencia, agradecería enormemente su ayuda.
