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...

My Fact/object (order) has multiple attributes and "due date" is one of them. A single rule is based on a combination of more than one attribute. My rule's when condition are dynamic and configurable by the end-user. An example of a rule's condition could be: when Order(dueDate < (some date), quantity > 1000) then //do something Dynamic rule here means that "some date" could be the current-date or it could be current-date + 2 days i.e configurable. The thread I'm talking about runs once a day to check the the due date condition. Now the problem is that if the object is not changed and we call fireAllRules() then even if the duedate condition is met then too the rule is not fired because the object is not changed.
