Issues creating multiple threads with Thread_FirstPost

[Nimlh?g]

I'm working on a script, which requires multiple threads to be posted in a newly created forum.

In order to do that, I've created a little function which takes some basic info like forumid, userid, title and post content, and creates a Thread_FirstPost datamanager instance and then saves the post.

This works like a charm .. only .. it'll post the first post, and then nothing. Once I call the function once, it simply won't do anything anymore after that.

What am I doing wrong here?

Function:

PHP Code:

// we'll be needing these :)
require_once(DIR .'/includes/class_dm.php');
require_once(DIR .'/includes/class_dm_threadpost.php');
function postThread( &$vbulletin, $forumid, $userid, $title, $text, $open=1, $sticky=0, $iconid=1, $allowsmilie=1 )
{


      $visible = '1';    // we want the post to be visible
      
      // need a datamanager to post a new thread
    $newThread =& datamanager_init('Thread_FirstPost', $vbulletin, ERRTYPE_ARRAY, 'threadpost');        
    
    $foruminfo = verify_id('forum', $forumid, 0, 1);    // post in this forum
    $newThread->set('forumid', $forumid);                // set the forumid
    $newThread->set('userid', $userid);                    // post as this user
    $newThread->set('pagetext', $text);                    // post this post
    $newThread->set('title', $title);                    // post with this title
    $newThread->set('allowsmilie', $allowsmilie);        // allow smilies, or not
    $newThread->set('visible', $visible);                // make the post visible
    $newThread->set( 'open', $open );                    // locked/unlocked
    $newThread->set( 'sticky', $sticky );                // sticky/unsticky
    $newThread->set( 'iconid', $iconid );                // post icon
    $newThread->set_info('forum', $foruminfo);            // set the forum information
    $newThread->save();                                    // save the post
    unset( $newThread, $pagetext );
} 


Any suggestions?
