Yes, of course. It was not copy-pasted from my code directly. I tried to make an example. Maybe there is a problem in DataObject since I have to use an older version of it (0.19). I Cannot update because my web hoster only provides a version of php lower than 4.3 and PEAR is not even installed on the server. I have to manage using PEAR on that server myself. Does anybody know if there was a problem with getLink() in version 0.19 of DataObject? While debugging, I found a weird statement on line 220 of DataObject.php in methode get(): $this->$k = $v; Also the statement on line 221 seems to be strange: return $this->find(1); Any ideas? -- Cheers!
