Re: [rules-users] Declaring an entry-point? (drools 5 M1)

Thanks Edson, Will try that out. One more question, when my pattern matches against the event, am I to assume the pattern matching in the order the events were placed or do I have to define additional matching statements on the pattern (i.e. comparing against a timestamp) to ensure I am matching against the most recent event?
