Does not work on comments fields in panels

this is a quick shot in the dark
let me know the outcome

Perhaps this should be in the panels queue?

I'm sure the problem is in this module
but I'm disinclined to set up a D5 with some 5.x modules

nevertheless, this problem might be present in 6.x version

how is the URL of those pages? (I mean without considering aliases, e.g. user/1/edit)
do you have Devel enabled? (having you to "Execute PHP" might help a lot, in a testing environment, of course)

what I would like you to do is to enable the "Execute PHP" block (comes with devel)
place it in a sidebar (or footer, whatever region you want)
so I can provide some snippets to figure where the problem might be

Note that I haven't examined D5 for API change,
so we might jump into incompatibility errors while trying to test these snippets (D6)

first, check that a proper comment_form is built

  $comment['subject'] = 'test';
  $comment['comment'] = 'testing';
  $form_state = array();
  $form = drupal_retrieve_form('comment_form', $form_state, $comment);
  print_r($form['subject']);

then, look for an existing node id to test how the subject is built

  $nid = 11; // an existing node id (nid)
  $comment['nid'] = $nid;
  $comment['comment'] = 'testing';
  $form_id = 'comment_form';
  $form_state = array();
  $args = array($form_id, $comment);
  $form = drupal_rebuild_form($form_id, $form_state, $args);
  print_r($form['subject']);

and finally, look for an existing comment id to test how the subject is built when replying to another comment

  $cid = 30; // an existing comment id (cid)
  $comment['pid'] = $cid;
  $comment['comment'] = 'testing';
  $form_id = 'comment_form';
  $form_state = array();
  $args = array($form_id, $comment);
  $form = drupal_rebuild_form($form_id, $form_state, $args);
  print_r($form['subject']);

Note: for these test just pick up any $nid or $cid (of an existing node or comment respectively)
it doesn't matter if they're related, not even if comments are enabled
the form should be built on these arbitrary demands

yes, it is relevant for 6.x as well (is the same approach there, no consideration for comments out of node/* & comment/* paths)

however, I ask you to brake it again (in your dev server) to confirm that it is working thanks to the proposed patch

when you find the time, unpatch it (and if needed clear cache, re-enable it or what so ever, which BTW doesn't makes sense unless having some enabled cache getting in the middle)
and please, report back your results to make it official

thanks for your feedback

thanks

Can somebody post the patched module for 6.2 dev? I'm not developer, I'm not able to apply patches...

for 6.2 dev?

the proposed fix would be applicable to 6.x-1.x, but not for 6.x-2.x

post the patched module

I don't think someone will post the whole module with a patch applied
if you're interested on making it work for 6.x-1.x you can copy the lines prefixed with a plus sign (see the patch) between lines 44 and 45 of the comment_subject.module file (version 6.x-1.x)
(or you may ask for a 6.x-1.x patch, but it seems that you won't know how to deal with it)

Nevermind my earlier comment I've learned about patching. :p

@#14 then for 6.x-1.x here you are

Thanks arhak. :p
