[rules-users] Fwd: 5.3.0 Final - Rule using accumulate with windows:length delivers an unexpected result

I'd have to defer to the drools-expert people.. as the problem appears to be with 5.3.0.Final of drools-expert. As a reminder, the DRL failing in 5.3.0.Final (or giving different results to 5.2.0?) is:- rule "Event Processing Evaluation" dialect "mvel" when $list:java.util.List() from collect( evalEvent(wam == 'D1', f != null)over window:length( 1 )) $average:Double() from accumulate( evalEvent($vf:f) from $list,average($vf) ) eval($average > 5) then internalEvent fact0 = new internalEvent(); fact0.setDesrc( "Internal Event: "+ $average ); insert(fact0 ); end ---------- Forwarded message ---------- From: axel <axel.poeschmann(a)solutions.endress.com&gt; Date: 14 November 2011 08:16 Subject: Re: [rules-users] Guvnor (5.3.0 Final)- Rule using accumulate with windows:length delivers an unexpected result To: rules-users(a)lists.jboss.org Thanks Mike. So, now I've included Drools 5.3.0 Final in my Eclipse Drools Project too and discovered the same problem as in Guvnor with my example. There is a difference between 5.2.0 Final (works well) and 5.3.0 Final (fails) in my case. Is there a major change with event processing with sliding windows or is it a just bug in the new version? The DRL between Eclipse and Guvnor is the same, in principle. It means, I started the project within Guvnor using the build features with the Editor supporting creating a model in Guvnor and the business rule. These two files, I couldn't reuse in my Eclipse project 1:1 (I used New File from Guvnor Ressource in Eclipse for that), failed to compile and even to open for the brl-file. So, I made the same model as Java Classes and a new DRL in Eclipse copy the stuff from the Guvnors view source windows adding the includes for the Java model and adding the Event declaration by hand. By the way, are there any other hints for that ... With regards, Axel -- View this message in context: http://drools.46999.n3.nabble.com/rules-users-Guvnor-5-3-0-Final-Rule-usi...
