Just got through troubleshooting why my grid wasn't sorting in descending order on my groupField. It worked fine in Ext 2.2 but just upgraded to Ext 3.2.1. After looking through the source code I found an undocumented config called groupDir and setting it to 'DESC' fixed by problem.


I also think this is a bug but maybe there is another undocumented config to get clicking on the column headers to also sort the groupField if the column is the current groupField?
