[rules-users] How to get a rule fired when the object is not changed?

As i understand the rules get fired on a fact/object when it is modified and the workingMemory is notified of the change. I have a requirement where one attribute of a fact is time based (due date of an Order object) which is a static field but i need to run a thread that periodically compares the current date with this attribute so that i can fire a rule when the system date matches with the due date. Now since the object is not modified simply calling fireAllRules() by this thread is not working for me. A workaround that i have is to retract and assert (or modify) that object everytime that thread calls fireAllRules() but in that case i need to call modify on all Order objects lying in the working memory. Is there any better way to achieve this? thanks, Faizan -- View this message in context: http://www.nabble.com/How-to-get-a-rule-fired-when-the-object-is-not-chan...
