Or even this:

sub render : ActionClass('RenderView') {}
sub end : Private {
   my ($self,$c) = @_;
   $c->forward('render');
   if (my @errors = @{$c->errors}) {
     $c->errors(0);
     $c->stash->{template} = 'error.tt';
     $c->stash->{errors} = \@errors;
     $c->forward($c->view('TT'));
   }
}

To allow for a templated error page.

Best,
Brian
