<div>Have you ever tried out to insert the events into the WorkingMemoryEntryPoint "EventStream" directly that you have commented out in your execute method?</div><div>and read the window from that eventstream in your rule, that is, "window:length( 5 ) from entry-point EvenStream".</div>
<div> </div><div>Of course, the second rule will fire also if it would be no event but a simple fact for drools.</div><div>Unfortunately, I do not know under which condition the default entrypoint is populated.<br><br></div>

Tried, but won't work.<br>
<br>
Ok, step by step.<br>
<br>
1- DRL File<br>
<br>
Event declared, FirstRule won't work and SecondRule is working properly<br>
(neither count or sum)<br>
<div class="im"><br>
declare StateEvent<br>
@role( event )<br>
end<br>
<br>
</div>rule "FirstRule"<br>
<br>
when<br>
Number( $total : doubleValue ) from accumulate(<br>
StateEvent(itemName=="Temperatura", $val : newState) over<br>
window:length( 5 ),<br>
count ( 1 ))<br>
then<br>
System.out.println("" + $total);<br>
end<br>
<br>
rule "SecondRule "<br>
<br>
when<br>
StateEvent(itemName=="Temperatura", $val : newState)<br>
then<br>
System.out.println("" +<br>
((DecimalType)$val).toBigDecimal().doubleValue());<br>
end<br>
<br>
2. Important lines from Engine starting (notice that i'm using stateful<br>
session)<br>
<br>
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();<br>
<br>
kbuilder.add(ResourceFactory.newClassPathResource(RULES_CHANGESET,<br>
getClass()), ResourceType.CHANGE_SET);<br>
<br>
KnowledgeBaseConfiguration kbaseConfig =<br>
KnowledgeBaseFactory.newKnowledgeBaseConfiguration();<br>
kbaseConfig.setOption( EventProcessingOption.STREAM );<br>
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(kbaseConfig);<br>
<br>
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();<br>
<br>
