-----------------------------------
Summary: CCE modifying a polymorphic object over a window
Key: DROOLS-1501
URL: https://issues.jboss.org/browse/DROOLS-1501
Project: Drools
Issue Type: Bug
Components: core engine
Reporter: Mario Fusco
Assignee: Mario Fusco
Modifying an object matched in a polymorphic way and using a window like in this test
case:
{code}
@Test
public void testModifySubclassOverWindow() {
// DROOLS-
String drl = "declare Number @role( event ) end\n" +
"declare Integer @role( event ) end\n" +
"\n" +
"rule R1 no-loop when\n" +
" $i: Integer()\n" +
"then\n" +
" update($i);\n" +
"end\n" +
"rule R2 when\n" +
" $n: Number() over window:length(1)\n" +
"then\n" +
"end";
KieSession ksession = new KieHelper().addContent( drl, ResourceType.DRL )
.build( EventProcessingOption.STREAM )
.newKieSession();
ksession.insert(1);
ksession.fireAllRules();
}
{code}
causes a CCE like the following:
