Duplicate Suggestions Using Tagging and Extractor

Weird, the screenshot didn't make it into Drupal.org. I've never had this problem before. Trying to attach again...

Can you explain how to check if the hook is called twice?
Thanks,
Tim

Eugen,
You were right. It looks like nearly the exact same code is being called twice, once in the tagging module and once in the tagging_extractor_suggest module. I guess the code in the tagging module is left-over from before you created the sub-module. Below is the code straight out of each .module files.

tagging/tagging.module

    $terms = extractor_extract($node->body);

    $result = array();
    foreach($terms as $key => $term) {
      $result[] = array('#weight' => (1/$key), '#name' => $term);
    }
    $suggestions = $result;

modules/tagging_extractor_suggest/tagging_extractor_suggest.module

  $terms = extractor_extract($node->body);

  $result = array();
  foreach($terms as $key => $term) {
    $result[] = array('#weight' => (1/$key), '#name' => $term);
  }
  return $result;
}

So, for now, I've disabled the tagging_extractor_suggest module because the code is running twice due to that module being enabled. With the sub-module disabled I get one suggestion for each term as expect.
