Check the result of

Re: [rules-users] Help with event not found over window query
On 18 Feb 2014, at 18:38, laune [via Drools] wrote: [snip] I ran into trouble because my various rules (from my original email) wouldn't fire an alert as expected when I fed in simulated events. I'm curious as to why you think it's interesting that the four rules below fail to meet my expectation? I suppose it's the fact that I'm a drools newbie and the issue here is probably just my inexperience mapping business logic into drools rules. The word is illuminative rather than interesting. Take this one: $e1: Event($location: properties[location] ...) not Event(, this after $e1) The $e1 Event is here, Time is Now. It's most certainly true that nothing is here after Now! - And the next one: $e1: Event($location: properties[location] ...) not Event(, this after[0, 1m] $e1) Again, Event $e1 is here, Time is Now, and nothing is here after Now. The operator does not instruct the Engine to wait! Yes, I had imagined something like that was the case. My original reasoning was the following; At the moment when the $e1 event arrives, time is Now and it is true that there is no second event. However, there is no way for the engine to know at Time=Now whether or not the second event is going to arrive within the required time period (this after[0,1m] $e1) Surely, the engine needs to wait until (at least) Time=Now+1m before firing the rule, at least in the second case, because it is not possible to establish the truth or falsehood of the second criterion until 1m has past since the first event arrived because the second event might arrive, right? Well, that's what I thought at least! daveor -- View this message in context: http://drools.46999.n3.nabble.com/Help-with-event-not-found-over-window-query-tp4028129p4028190.html Sent from the Drools: User forum mailing list archive at Nabble.com.___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] OutOfMemoryError using 6.0.1
A workaround in optaplanner 6.0.1 is probably to enforce RETE_OO (unfortunately ScoreDirectorFactoryConfig#buildKieBase hard codes that, so that's a PITA). It's fixed in BRMS 6.0.0.GA and optaplanner 6.1.0.Beta1. optaplanner 6.1.0.Beta1 might be released later this month.
