Collect and accumulate conditions not working together ------------------------------------------------------ Key: DROOLS-173 URL: https://issues.jboss.org/browse/DROOLS-173 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 6.0.0.Beta3 Reporter: Alvaro Pantoja Assignee: Mark Proctor Attachments: rule-test.log Running this example: > import java.util.ArrayList > > declare Item > code: int > price: int > present: boolean > end > > rule "Init" > when > then > insert(new Item(1,40,false)); > insert(new Item(2,40,false)); > insert(new Item(3,40,false)); > insert(new Item(4,40,false)); > end > > rule "CollectAndAccumulateRule" > when > //At least two items that aren't presents > objList: ArrayList(size>=2) from collect( Item(present==false)) > //Total price bigger than 100 > price: Number(intValue>=100) from accumulate( Item($w:price, present==false), sum($w)) > then > > System.out.println("Sum: "+price); > System.out.println("Items size: "+objList.size()); > > //Look for the minor price item > Item min = null; > for(Object obj: objList){ > if (min!=null){ > min = (min.getPrice()>((Item)obj).getPrice())?(Item)obj:min; > } > else { > min = (Item)obj; > } > } > > //And make it a present > if (min!=null){ > modify(min){setPresent(true)}; > } > end Leads to an extra activacion and execution of rule "CollectAndAccumulateRule". It doesn't matter wich order conditions have, as long as there ara an "accumulate" and a "collect". Expected output would be: Sum: 160.0 Items size: 4 Sum: 120.0 Items size: 3 But is: Sum: 160.0 Items size: 4 Sum: 120.0 Items size: 4 Sum: 120.0 Items size: 3 Find attached agenda and working memory log snapshot
