i want to set condtions to _has_many relation so i'm having this code, that generate an sql querry with erros, i'm having is not `` instead of is not null
ON (`t0`.`id` = `t2`.`queue_id` AND `t2`.`advisor_connected_at` IS NOT ``)
I have fixed it in 1.8/develop, the fix will be part of the 1.7.2 release. If you need it you can backport fuel/core/classes/database/query/builder/join.php to 1.7.1 without problems.
