Hi,
it is a matter of cell selection in grid.
After data arrived I select programmatically some cell. If I start to navigate with arrow keys -> or <- the first time it jump to a some random cell. After that one can navigate as one expects.
How can I solve it?
I adapted some class from Showcase:
Thank you in advance,
