TMSFMXGrid: access violation on Ungroup

FMX TMS FMX UI Pack
1

My environment:

Delphi XE4 Update1 + Mobile
iPad iOS 6.1.3
TMS Pack 2.2.1.1
 
I'm testing the GroupDemo project on my iPad but, when I click on Ungroup button, I get an "access violation".
This exception occurs at line 4792 of FMX.TMSGridData:
ClearCells(CellRange(0,i,ColumnCount - 1,i));
 
How can I solve this problem?
Thanks.

Hi, 


We are unable to reproduce this here, did you select a row, or scrolled the grid before clicking the Ungroup button?

Kind Regards, 
Pieter

No, I simply clicked on the Group button, and then on the Ungroup
button.<?: prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>
