Dear wise monks,

it appears i'm running into an error with CGI::Application and CGI::Ajax.

CGI::Ajax says that it "checks to see if a header() method is available to the CGI object, and then uses it. If method() isn't available, it creates it's own minimal header."

This is all fine and dandy, but when i run my code (shown below), it returns this error:

No head/html tags, nowhere to insert. Returning javascript anyway

package Notes;

use strict;
use CGI::Carp qw[fatalsToBrowser];
use CGI::Ajax; # hope it plays ok with C::A...

use base 'CGI::Application';


my $pjx = CGI::Ajax->new ( 'export' => \&print_input );
sub setup {

  my $self = shift;
  $self->mode_param( "m" );  # mode param in query string
  $self->start_mode( "main" );  # starting run mode
  $self->error_mode("fatal_error");
  $self->tmpl_path("tmpl/");
  
  # other run modes
  $self->run_modes (
  
    'main'         => 'main',
      
  );

}

### main page of the website
### when linking back to it, it's easiest to use
### <a href="?">home</a>

sub main {
    
    my $self = shift;
    my $q = $self->query;  # the CGI object
    my $tmpl = $self->load_tmpl( 'main.tmpl' );

    $pjx->build_html( $q, \$tmpl->output );
    
}

sub fatal_error { 
    
    my $self = shift;
    my $error = $@;
    return $error;
    
    
}


## ajax functions

sub print_input {

    my $input = shift;
    
    return ($input . " was the inputted value");
    
}

Is CGI::Application not returning header tags that CGI::Ajax likes?

Please enlighten me.

meh.
