In one of the projects we’ve implemented soft-delete protection (on the first delete attempt an IsDeleted=1 flag is set instead of fully deleting the db record; on the second delete attempt the record is deleted from the database). To make it work, the “kDBEventHandler::customProcessing” method was used.

The problem is that other deletion-related events (e.g. “OnDelete” and “OnDeleteAll”) aren’t calling the “kDBEventHandler::customProcessing” method and therefore continue to delete record from the database on the first attempt.
