>How do you usually handle parent-child in this case

I have used codemine for the last few years and one of the standard forms is child data form. I haven't checked but think I can have a child data form call a child data form (at least in version 7).

At the moment I'm leaning toward creating a master form with a grid that will call children to make selections. The grid will allow for a very large number of selections and can be reviewed by selection easily.

The question of special rules for some the selections is another issue. I'll have to design some class that is called just before and after a selection is made. I might be able to use the builtin classes from codemine. Codemine does have beforenew and afternew methods and I will (most likely) use them to trigger my class methods.

I see the methods returning information that is data driven to account for all the small special requirements.

Thanks for your help.
