Generating nodes with FileField creates many files for each node generated

I have a node with 3 CCK file fields. When I use the devel module's generate functionality to create nodes, FileField is creating over 250 files for each node generated.

So if I generate a single node, I will have 250 files in my uploads directory. It properly assigns 3 files to the node, but I tried creating 50 nodes and then I ended up with over 7000 files in the database and on the filesystem.

I believe this is hooked into the generate functionality in filefield_content_generate. This function gets called way more than 3 times per node generated.

I attempted adding a static array here so it could "remember" which fields it has been called for:

  static $fields_generated = array();
  
  if (in_array($field['field_name'], $fields_generated)) {
    return;
  }
  
  $fields_generated[] = $field['field_name'];

That works so that it only creates 3 files on the filesystem and in the database, but it does NOT associated them with the auto-generated node. Maybe someone with further knowledge of this code can see where I'm going wrong. These CCK file fields only accept 1 value (file).
