HTML::FormFu::Filter::CopyValue - copy the value from another field

   elements:
      - type: Text
        name: username
      - type: Text
        name: nickname
        filters:
           - type: CopyValue
             field: username

Filter copying the value of another field if the original value of this field is empty.

If the original field contains an invalid value (a value that will be constrained through a constraint) that invalid value will be copied to this field (the field with the CopyValue filter). So, the user has to change two fields, or you can remove the invalid value in a custom constraint.
