[jboss-jira] [JBoss JIRA] Created: (JBRULES-2433) Facts with event roles in process constraints cause exception

Facts with event roles in process constraints cause exception ------------------------------------------------------------- Key: JBRULES-2433 URL: https://jira.jboss.org/jira/browse/JBRULES-2433 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Reporter: Paul Borlin Assignee: Mark Proctor When the following conditions are met, a runtime exception is thrown when the following said type is inserted into working memory: 1. A ruleflow and rule definition are asserted into the knowledgebase 2. The rule definition declares a type as being an "event". (declare myType @role( event ) @timestamp( value ) end ) 3. The ruleflow references that type in a constraint. 4. A rule in the rule definition has a LHS constraint that references that type as an event (i.e., code such as "over window:time( 12M )" is used) Attached is a JUnit test that reproduces issue. The following stack trace is the result: java.lang.ClassCastException: org.drools.common.DefaultFactHandle cannot be cast to org.drools.common.EventFactHandle at org.drools.rule.SlidingTimeWindow.updateNextExpiration(SlidingTimeWindow.java:198) at org.drools.rule.SlidingTimeWindow.assertRightTuple(SlidingTimeWindow.java:120) at org.drools.rule.BehaviorManager.assertRightTuple(BehaviorManager.java:88) at org.drools.reteoo.JoinNode.assertObject(JoinNode.java:186) at org.drools.reteoo.SingleObjectSinkAdapter.propagateAssertObject(SingleObjectSinkAdapter.java:42) at org.drools.reteoo.AlphaNode.assertObject(AlphaNode.java:147) at org.drools.reteoo.CompositeObjectSinkAdapter.doPropagateAssertObject(CompositeObjectSinkAdapter.java:360) at org.drools.reteoo.CompositeObjectSinkAdapter.propagateAssertObject(CompositeObjectSinkAdapter.java:337) at org.drools.reteoo.ObjectTypeNode.assertObject(ObjectTypeNode.java:184) at org.drools.reteoo.EntryPointNode.assertObject(EntryPointNode.java:146) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:1093) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:1044) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:829) at org.drools.impl.StatefulKnowledgeSessionImpl.insert(StatefulKnowledgeSessionImpl.java:233) at com.company.RuleFlowTest.pepPostEvent(RuleFlowTest.java:83) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
