Hi,
I am facing a similar issue, after I upgraded from 3.7 to 4.2.
I have 2 rows selected in the grid, and both checkboxes are also shown checked.
But when I uncheck one checkbox to deselect it, other checkbox also gets unchecked, althouth the other item shows selected(highlighted – css).
This is really wierd and I am not able to crack it.
Anyone has any idea?
Jimmy.
