-----------------------------------
Summary: ClassCastException when adding a type declaration with incremental
upgrade
Key: DROOLS-1395
URL: https://issues.jboss.org/browse/DROOLS-1395
Project: Drools
Issue Type: Bug
Components: core engine
Reporter: Mario Fusco
Assignee: Mario Fusco
The addition of a type declaration during an incremental compilation like the following:
{code}
declare OtherDummyEvent
@role( event )
@timestamp( timestamp )
end
{code}
is not reflected in the existing knowledge base. For this reason also adding a new rule
like this
{code}
rule "RG_TEST_2"
when
$event: DummyEvent ()
$other : OtherDummyEvent(id == $event.id, this after $event)
then
System.out.println("RG_TEST_2 fired");
retract($other);
end
{code}
and inserting an OtherDummyEvent causes the following ClassCastException :
{code}
ClassCastException: org.drools.core.common.DefaultFactHandle cannot be cast to
org.drools.core.common.EventFactHandle
{code}
because the instance of OtherDummyEvent is considered a fact instead of an event.
