Show comments on wordpress home page

Question

I've inserted the following code to the template loop (in the correct place), but it is not outputting any comments. Why?

<?php
    $withcomments = true; // force comments form and comments to show on front page
    comments_template( '', true );
?>

I'm trying to display comments for each post on the main-home-page stream of posts.

I'm using the Twenty Ten theme.

Answer 1

Try this before the <?php endwhile; ?> of the loop in loop.php:

<?php
  $withcomments = "1";
  comments_template();
?>

Answer 2

Try this:

<?php global $withcomments; $withcomments = 1; comments_template(); ?>
