It's even worse: the record of the "rubrik" bizobj not only doesn't move, it gets the key of the record just shown in the dropdown. And that key is the primary key of the table. Wonderful. Luckily I haven't done anything about saving yet. It's clear I made quite wrong assumptions about dDropdownList (and about the other list controls?). I thought moving through the choices list would move through the records of the dataset and show the content of the current DataField, but instead it seems to put the current value _into_ the DataField of the current record, which doesn't move.

We are talking about a database table with 14 records here.
