i write a rule like this rule when Now( now ) Fact( attrib ) then //do something end Using a Thread with fireUntilHalt( ) Method. and then i update the Now regularly, and after that i insert a new Fact. the problem is that , when i update the Now( ) , the rule fired , and i insert the Fact, the rule fired again ! How can i make the update operation do not trigger the rule , while just fire the rule when i insert the Fact ? -- View this message in context: http://drools.46999.n3.nabble.com/make-the-rule-not-to-fire-when-insert-o...
