Integrate Komento with J-BusinessDirectory

Hello,

I would like to integrte Komento with J-BusinessDirectory.

I have followed the instructions provided in http://stackideas.com/docs/komento/integrations/creating-your-own-integration-files but can't seem to load the data correctly, I keep getting the error:

Warning: array_key_exists() expects parameter 2 to be array, null given in ../public_html/components/com_komento/helpers/helper.php on line 638

The table name is: jbusinessdirectory_companies
And I'm using:

$query->select('a.id AS id_field, a.name AS title_field, a.typeId AS catid_field, a.viewCount AS hits_field, a.userId AS created_by_field');
$query->from($db->quoteName('#__jbusinessdirectory_companies').' AS a');


Could you please help me make this happen?

Kind Regards,
Ignacio
