I can see Scriptcase has a OLD Bug with the forms. :(
I have a form with my table products. This form has a field Quantity (readonly and for update has Calculated by the database). So the it can not update this field in mode update.
BUT, if i have el form running, and i then i update manually the field Quantity for the table Productos with a SQL or Other form… AND Then in the form Products Press the Save Button, It Saves fine (No update the field quantity)… BUT if press the SAVE BUTTON AGAIN… The Form Updates the Value in the field Quantity.
Other error that occurs with this read-only fields is that if at the time of add new record, when the new record saves and there is some validation error, the read-only fields allow data to be entered.
