Hi Yosry,
It's failing for me as well. I debugged and found that, sometimes the grid
render is delayed (in microseconds) after query execution. Because of
which, the cell you had selected using xpath is actually the older one. And
when you're trying to set the value the cell no longer exists as the new
cell is rendered now. That's why stale element exception. Adding below code
solved the problem for me. Attached is the patch.
import time
time.sleep(0.5)
for column_index, should_be_editable in enumerated_should_be_editable:
