Hi Mario,
The problem in the DBIC::Validation case is that DBIC is deleting all the
dot parameters before FormFu can even see them. Here is the DBIC code from
DBIx::Class::ResultSet:

sub new_result {
  my ($self, $values) =3D @_;
  ...
  my %new =3D (
    %{ $self->_remove_alias($values, $alias) },
    ...
  );

  return $self->result_class->new(\%new);
}

That _remove_alias method is deleting all the dot parameters so my redefined
"new" method in DBIC::Validation::FormFu never gets them.

I can resolve it in my side using Hash::Flatten to recreate the dot
parameters to pass to FormFu, but I thing that that should be handled by
FormFu. That way you can get a CGI::Expand, JSON or YAML structure and pas
it directly to FormFu to be validated.

What do you guys think?

Cheers,
