Create a method called "showForm" that is called as the final step in
each run mode and put your menu UI configuration stuff there. Do your
context specific stuff in each individual run mode.

I have used this approach with gooed results.

 sub runmode1
 {
 	...
 	
  # your runmode1 logic goes here
 	...
 	return $self->showForm( $template ); 
 }

sub showForm {
  ... 
 
  $tmpl->param(par1 => $foo);  
 	$self->populate_menu( $q, $tmpl ); 

  return tmpl->output;
}

The above pseudo-code assumes that you will be passing
an HTML::Template instance to "showForm".

cheers,
