[DB][DataObject] links.ini

Dear people: Alexey Borzov suggested me looking to DB_DataObject FormBuilder. While setting up DataObjects and fumbling with foreign key relations there rised a question reg the mydbname.links.ini-file: http://pear.php.net/manual/en/package.database.db-dataobject.db-dataobject.getlinks.php they say that the syntax of the links.ini-file should be something like this: [person] person_id = convention:person_id I just dont really understand this. I would think that I would need to set up something like this: [person] convention_id = convention:id ,because I want to 'say' that in table "person", the field convention_id is linked to the (primary key) field id in table convention... am i blind or is there something wrong in the manpages? Manually invoking a join via getLink() works perfectly tho. Unfortunately a try like the example below doesnt work for me, as well. I read that naming conventions are deprecated - maybe thats the source of my or the manuals confusion? Thank you, Matthias
