DB_DataObject sorting links-results

i got a question about DataObjects. after getting the linked tables, i would like to have the multiple results sorted by a column how do i do that? what i got now is without sorting

    $contact = new DataObjects_Contact2tree;
    $contact->contactTree_id = $session->temp->folder->id;
    $contact->find();

    while( $contact->fetch() )
    {

// link the column 'contact_id' to the table 'contact' // which contains columns like 'name' 'surname' etc.

        $contact->getLinks();

print_r($contact);

    }

i.e. i want to sort by 'contact.name', is that possible? if so, how? the query would be: SELECT * FROM contact2tree ct,contact c WHERE ct.contact_id=c.id ORDER BY c.name but since i am reading the contact2tree table first, when using the DataObject i have no idea how to sort by the content of a table i will 'link'/'join' later -- Wolfram ... translating template system ... http://sourceforge.net/projects/simpletpl now also as PEAR-package available ... authentication system .... http://sf.net/projects/auth ... and more at .... http://opensource.visionp.de
