The answer is yes. My actual code is pretty similar to yours.

sub build_redirect
{       
  my ($self, $form, $script) = @_;
    
  $form ||= {};                                                       
+          
  my $q = $self->query;
  my $uri = URI->new( $script || $q->script_name );                   
+          
  $uri->query_form(%$form);                                           
+          
        
  return $uri->as_string;
}       
        
sub redirect
{       
  my $self = shift;                                                   
+          
    
  $self->header_add( -uri => $self->build_redirect( @_ ) );           
+          
  $self->header_type('redirect');                                     
+          
}

If you want to switch run modes in mid-stream your current run mode just has to call the runmode that you want.

There is never any need for a normal CGI::Application based app to use redirect headers to access another runmode unless the resource has actually moved (e.g. has a new URL)

Here is larsen's example modified updated to remove the redirect.

# Does nothing except printing the form.
# Using sessions you can pass to it an error_message,
# for example.
#
sub login                                                             
+          
{   
    my $self = shift;                                                 
+          
    
    my $tmpl = $self->load_tmpl( 'login' );                           
+          
    
    return $tmpl->output();                                           
+          
}   

sub login_update                                                      
+          
{   
    my $self = shift;                                                 
+          
    my $q    = $self->query;
  
    # Fetch username and password from the form
    #  
    
    if ( PASSWORD CORRECT ) {        
        
        return $self->first_panel;           
    }
    else {

        # It could store some useful info in a session,
        # for example the error message.
        #
        return $self->login;
    }

    # You have a problem if this return ever actually executed
    #return;

And can you tell me what happens when users hit reload on their browsers? If you redirect users, they will not be able to reissue a command by reloading the login_update run mode. Nice, isn't it? :)
