default date when current value is null

[melquelima]

i have this column 'dt_envio_cyber' initialy as NULL

when i click to edit it:
it automaticaly sets current datetime

the issues is: when i click to save the changes:

i`ve being analising it, and i noticed:
1 - query sent is not populating "${payload.dt_envio_cyber}"

2 - i have to open the date and hit "apply" then it works
