Hello Maksim,
I would like to know have you done any changes in the refresh() method from 1.1 to 2.1.1 Pro.
Initially we were using the 1.1 Version in our project, and every thing was working perfectly, but when we have migrated to 2.1.1 Pro, the refresh() method is not reflecting the changes.
and also I would Like to know that, my treetable, data is coming in reverse order.
