I need to add rule for filtering an event for 2 hrs. i.e. The action would be taken once event has occurred for the first time & then all the events of the same type would be ignored two hours & action should again take place if event has occurred anytime after 2 hrs. How should this be written using Temporal relations or sliding window features? Or are there any other ways to write the same? -- View this message in context: http://drools.46999.n3.nabble.com/how-to-use-temporal-relation-sliding-wi...
