Form DML throws "No checksum found for lost update detection"

D-FilesAug 26 2021 — edited Aug 26 2021

Hi there,

I'm facing following problem.
I have a form with a DML process where the "creating" part works fine, but updating and deleting runs into "No checksum found for lost update detection. Can only perform UPDATE or DELETE for existing rows."
The form is based on a table, ROWID is included and "lost update type" is in "row values".
The necessary items have in "Source" the form region and column and data type are as of the corresponding table columns.
"Maintain Session State" is on "Per Request".
The DML process has "Target Type" on "Region Source", "Prevent Lost Updates" is true (when its false, it doesn't save my changes), "Lock Row" is "yes" and "Return Primary Key(s) after Insert" is true.

What am I missing??
