ListGrid: grouping by a Date field

[elconiglio]

Hello, I've tried to group a ListGrid by a Date field (which is formatted as dd-MM-yyyy by a custom CellFormatter) but something gone wrong. Each row had its own group (all groups had the same name, a non-formatted date representation - Thy May 20 2010 00:00:00 GMT-0300).

Am I doing something wrong? I could just turn the field to a String but the sort wouldn't work well with the dd-MM-yyyy pattern.

Thanks,
elconiglio

Hey have u tried grouping by using field.setDateFormatter() to apply pattern instead of custom cellFormatter.
