Mario Fusco created DROOLS-1395: ----------------------------------- 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. -- This message was sent by Atlassian JIRA (v7.2.3#72005)
