Sounds promising! Thank you to you and Joel for contributing code. Peter knows the DG better than I do so hopefully he'll look at it tomorrow. I'm wondering though, from the description below, is there a model bead involved somewhere? I would expect to have a model bead store the sort information (which column is being sorted, and whether ascending or descending. That way the customer can set the model to have an initial startup sort. Or is that taken care of some other way?
