Re: [rules-users] on update

Folks, I need a rule that will track changes to cost amount and do something with his old value. Like that : rule "on updated cost write to archive old value" when cost : Cost() old_cost : Cost(amount != cost.amount) // how can I specify the OLD cost object before it was updated??? then ... write to archive $old_cost.amount end Is it possible at all? Something like in database system triggers, when you have "on update" and then you have OLD value and NEW values available...?
