We'll review and implement
In order to make autoinc fields work in awserver.PropsRestore_DS_Alias_cXMLcursor you need to adjust the code as shown here:
* ------------------------------------------------------------HIDDENPROCEDURE PropsRestore_DS_Alias_cXMLcursor && Curseur chargé avec les données XMLLPARAMETERS tcXMLLOCAL laField[1], liField, lnSelect, lcResult&& CursorToXML() ne rendant pas les valeurs nulles,&& créer un curseur dont les champs sont .NULL. par défaut FOR liField = 1 TOAFields(laField)* TBV* The first row is the table itself, and if that has* triggers in it , goodnigt charlie creating and updating the cursor.
