Just to make the answer available to other that might have the same problem,
I had to deactivate the framework code and handle the cursor from the
databrowser manually.

It also fixed a performance problem since I only have one record fetched and
not all of them.  This makes the answer time linear (database dependant, of
course) no matter how many records I have on the database.
