Each action will have it's own formbuilder object instance. After you
return from the forward to another form action, $self->formbuilder
will be a brand new FormBuilder object.

sub foo : Form('foo') {
   my ($self, $c) = @_;
   # $self->formbuilder is for foo form
   $self->forward('bar');
   # now $self->formbuilder is for bar form
}

sub bar : Form('bar') { ... }

Consequently, each action should do it's own thing with it's
FormBuilder object -- e.g. validate, add or change form fields). Not
sure what kind of problem you are having as a result of this since you
didn't provide sample Controller code.
