AJAX Comments & Node and Comments Form Settings

I had a similar problem on my site where I could post once using AJAX and then it would throw an error every time. I found this bit in modules/nodeformsettings/commentformsettings/commentformsettings.module:

// on comment_form there's no $form['#node'] so we can't load the $node->type
		// we just take the argument
		// since we don't have node/nid when creating a comment on a separate form
		// we have to filter the two cases to check what argument to take and load
		// the node
		// TODO: find a better way to do this

So I figured that AJAX comments seem to handle this function just fine. I looked in ajax_settings.module and found some code that seemed to do the same thing in a better way. So I ended up switching this code (commentformsettings.module starting at line 103):

 if(arg(0) == 'node' && is_numeric(arg(1))) {
			$node = node_load(arg(1));
		}
		if(arg(0) == 'comment' && arg(1) == 'reply' && is_numeric(arg(2))) {
			$node = node_load(arg(2));
		}
		if(arg(0) == 'comment' && arg(1) == 'edit' && is_numeric(arg(2))) {
			$node = node_load(arg(2));
		} 

With this code from ajax_settings.module (starting at line 113):

	if ($form['nid']['#value']) {
	    $node = node_load($form['nid']['#value']);
	  }
	  else {
	    $node = menu_get_object();
	    if ((!isset($node) || !$node->nid) && arg(0) == 'ajax_comments') {
	      $node = node_load(arg(2));
	    }
	  } 

It seemed to fix everything, and I was still able to add comments without AJAX Comments without breaking Comment Form Settings at all.

I would make a patch, but I'm pretty much a novice when it comes to Drupal. However, I think this code might be helpful for future versions of the module itself. Of course, the ajax code in there would have to be conditional or something, but it seems pretty close to what you would need.

I never used ajax comments before, but I'll give it a try to your method.
