>Is my assumption correct that if each of my forms launch w/Private Sessions, I will have to include some SET items to deal with the particulars of the form. i.e. While my app initially sets DELETED ON, the form in its Private Session doesn't recognize this. Is there a slick way around this or is it simply the reality of Private Sessions ? I don't build huge apps, so it isn't that much trouble to include a few SETs in the code of the Data Environment of the form.

Bruce,

Perhaps the best way to do this is to create a custom class to handle this chore. Steve Sawyer, in the "Effective Techniques..." book he wrote with Jim Booth, in Chapter 9 talks about this and some of the problems (albeit in some instances minor) that can occur with the various settings and private datasession. It's a terrific book.
