Last reply not show the user

This is a minor bug in version 6.x-alpha2 version.

It's created by this lines: (function: function advanced_forum_preprocess_forum_submitted(&$variables) )

// Format the author of the last post (node or comment)
    $author = new stdClass(); 
    if (!empty($variables['topic']->reply_author_id)) {
      $author->uid = $variables['topic']->reply_author_id;
      $author->name = $variables['topic']->reply_author_name;
      
    }
    else {
      $author->uid = $variables['topic']->topic_author_id;
      $author->name = $variables['topic']->topic_author_name;
      
    }

Why? Because the 'topic' variable doesn't has the reply_author_id, then, they show the username "Anonymous".

To fix it, i change the SQL for give the reply_author_id(i think that are a simply mistake :D) function: function _advanced_forum_get_last_topic($tid)

This is the original

// Get the most recently created node, in the given forum, that the user has access to
  $query = "SELECT n.nid AS topic_id,
                   n.title AS topic_title, 
                   n.created AS topic_timestamp,
                   n.type AS topic_type,
                   n.uid topic_author_id,
                   u.name AS topic_author_name
            FROM {node} n
            INNER JOIN {term_node} tn on n.nid = tn.nid
            INNER JOIN {users} u on n.uid = u.uid
            WHERE tn.tid = $tid AND n.status = 1
            ORDER BY n.created DESC";
            
  $node = db_fetch_object(db_query_range(db_rewrite_sql($query), array(), 0, 1));

  // If there is at least one node, then we need to look for the most recent comment       
  if ($node) {
    $query = "SELECT c.nid AS topic_id, 
                     c.cid AS reply_id,
                     c.timestamp AS reply_timestamp,
                     c.subject AS reply_title,
                     c.uid topic_author_id,
                     n.title AS topic_title, 
                     n.created AS topic_timestamp,
                     n.type AS topic_type,     
                     c.name AS reply_author_name           
              FROM {comments} c
              INNER JOIN {term_node} tn ON c.nid = tn.nid
              INNER JOIN {node} n ON c.nid = n.nid
              WHERE tn.tid = $tid AND n.status = 1 AND c.status = 0
              ORDER BY c.timestamp DESC";

i change the 2º query, and change c.uid topic_author_id, for c.uid reply_author_id, then, it show similar to:

  // Get the most recently created node, in the given forum, that the user has access to
  $query = "SELECT n.nid AS topic_id,
                   n.title AS topic_title, 
                   n.created AS topic_timestamp,
                   n.type AS topic_type,
                   n.uid topic_author_id,
                   u.name AS topic_author_name
            FROM {node} n
            INNER JOIN {term_node} tn on n.nid = tn.nid
            INNER JOIN {users} u on n.uid = u.uid
            WHERE tn.tid = $tid AND n.status = 1
            ORDER BY n.created DESC";
            
  $node = db_fetch_object(db_query_range(db_rewrite_sql($query), array(), 0, 1));

  // If there is at least one node, then we need to look for the most recent comment       
  if ($node) {
    $query = "SELECT c.nid AS topic_id, 
                     c.cid AS reply_id,
                     c.timestamp AS reply_timestamp,
                     c.subject AS reply_title,
                     c.uid reply_author_id,
                     n.title AS topic_title, 
                     n.created AS topic_timestamp,
                     n.type AS topic_type,     
                     c.name AS reply_author_name           
              FROM {comments} c
              INNER JOIN {term_node} tn ON c.nid = tn.nid
              INNER JOIN {node} n ON c.nid = n.nid
              WHERE tn.tid = $tid AND n.status = 1 AND c.status = 0
              ORDER BY c.timestamp DESC";

Sorry, i'm spanish and my english is too bad :(. I think that i place the "options" for this issue correctly, of course, you can modify it if they are wrong.
