Hi Vladimir,
Yes I can reproduce the problem by just using your testcase. The problem is in the grouping. I added group by name in your example, and do a select all and I get the exception when I more to the next page and get this problem
Line: 18
Error: Unable to get property 'up' of undefined or null reference
Can you please fix the bug as soon as possible, or better yet, propose a work around before your fix?
Thanks a lot.
