I have such a form too, It is modal with the default datasession so it can share the datasession with the calling form. If I don't need it modal (or for the debugging purposes I make it non-modal), it automatically detects the calling form's datasession and switches to it.
Can't say for everybody, but IMHO, I found that disadvantages of using the form set oughtweight the advantage of sharing the datasession.
