Pre-abmle: I am using MakeMeeting module to create/display meeting polls. This module has its own Content Type and I can't get comments to show on the screen (whether I choose to show comments or on same page or not in Comment Settings for this node type). The MakeMeeting module has it's own theme functions, but perhaps they're not guilty since Drupal must add comments to whichever data is produces by a module, as far as I know.

This brings up two related questions:

1) How can one use custom code to get comment functionality show up on custom CKK node? Most probably be this code should be added to node-typename.tpl.php

2) How can I debug why comments are not displayed, where should I check (function calls, variable names etc).

Thanks!
