[jboss-jira] [JBoss JIRA] (JBRULES-3373) Accumulate function doesn't work at all in 5.3.0 Final

[Juanker Atina (JIRA)]

     [ https://issues.jboss.org/browse/JBRULES-3373?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Juanker Atina updated JBRULES-3373:
-----------------------------------

    Steps to Reproduce: 
1. I'm setting the stream mode to work with events (kbaseConfig.setOption( EventProcessingOption.STREAM );)
2. I have a simple DRL file

declare StateEvent
	@role( event )
end

rule "Test"

when
	Number($total : doubleValue) from accumulate(
	        StateEvent(itemName=="Temperatura", $val : newState) over window:length( 5 ) from entry-point "EventStream",
	        average ( ((DecimalType)$val).toBigDecimal().doubleValue()   )  ) 
	
then   
	System.out.println("" + $total);
end

3. I insert a fact into working memory (entry point "EventStream")

WorkingMemoryEntryPoint entry = ksession.getWorkingMemoryEntryPoint("EventStream");
			entry.insert((RuleEvent) new StateEvent(item, state));

4. Fire rules

5. Repeat steps 3 and 4 to put accumulate and average functions to work


RESULTS WITH 5.2.0 Final

Works nicely, i can see the average updated with every fact inserted.

RESULTS WITH 5.3.0 Final

It returns the same result and average (neither sum or the simplest case count(1)) doesn't work.

then   
	System.out.println("" + $total);
end

3. I insert several facts into working memory (entry point "EventStream")

WorkingMemoryEntryPoint entry = ksession.getWorkingMemoryEntryPoint("EventStream");
			entry.insert((RuleEvent) new StateEvent(item, state));

4. Fire rules


RESULTS WITH 5.2.0 Final
