Code Igniter 3 - error on save with validation

[davide-lucchelli]

Hi guys,
I open a more specific issue.
I created a simple user model (like the example one), but when I try to save it with true parameter the model is not saved to db and errors array is empty.
Here is the code:

$User = new \Model\User();
$User->name = 'Davide';
$User->save();
print_R($User->errors);

Thanks,
Davide
