Steve (and anyone else interested), I have attached a simple P-O-C that demonstrates the problem.
If you remove the compareFunction attribute from the grid, the entries are grouped correctly; but of course, they're sorted randomly. However, with the compareFunction in place, the sort is correct. But there are multiple entries for each group. Any insight will be very much appreciated. -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560
