Hey, I am playing around with the new CEP features in 5 M1 and primarily working off of the blog posts and API doc. I have some patterns that pull from a stream: $candle : Candle( $instrument : instrumentSpecification ) from entry-point "candles" I have my entry point in the WM: candlesEntryPoint = this.session.getWorkingMemoryEntryPoint("candles"); I have also defined Candle to be an event in my rule.package file: import org.test.Candle declare Candle @role(event) end When I execute my sesson/getWorkingMemoryEntryPoint code above, I get a null back for the entry point and thus can't insert the event (Candle). The API docs for the getWorkingMemoryEntryPoint state that I need to define an entry point in the rules file? Is that the above part in the rule.package part or is that some other declaration? If that is a different declaration, is there some documentation what that would look like? The way I currently interpret the declare part is that I am designating my Candle object to be an event rather than a fact. Does that indirectly also declare an entry point? If so, how can I have heterogeneous streams with different object types? Thanks HC ------------------------------ View this message in context: Declaring an entry-point?

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?
