Hi,
Under Oracle APEX 24.2.11, I have two forms on the same table. On P.2 it is created and page is submited. Then we go to P. 11 with a another form with the same PK set from P. 2. However, I get a message “Aucun checksum trouvé pour la détection des mises à jour perdues. Opération UPDATE ou DELETE possible uniquement pour les lignes existants”. ("No checksum found Operations UPDATE or DELETE only for existing lines") when I submit the page 11. Here whe are in the condition “SQL UPDATE” for the button who submit the page. The primary key is well defined (it is 11139) I can see it (it is transmitted from P.2 to p. 11.). There are no double elements anywhere defined as Primary key.

Where does that error comes from ?
Best regards.
