Validate on form submit instead of input focus out

[liliangousiou]

Hello, I have used AvField for login validation. There are some checks that it is ok for validation to be triggered on input focus out, but I would like to get the validation result on form submit and also to add an extra custom check from backend. Is there any way to do this?
