Well, now it actually happened to me in a real scenario, I thought I had understood the part about creating a separate data session, but it didn't quite work the way I expected, as soon as the following line exewcuted:

set datasession to loSession.DataSessionID

the grid lost it's recordsource, (documentation does warn about using "set datasession to" when a form is active ) The preview worked correctly, the grid's recordsource still existed, but the records just wouldn't show on the grid.

Anyway, I looked at another one of my forms, that had a grid and had no problems with the preview, and the only difference was that the grid was inside a pageframe, so I put my grid inside a pageframe and the problem went away, which I find a bit odd.
