[jboss-jira] [JBoss JIRA] Resolved: (JBRULES-2321) Implicit binding and "or" CE in pattern cause ClassCastException

Implicit binding and "or" CE in pattern cause ClassCastException ---------------------------------------------------------------- Key: JBRULES-2321 URL: https://issues.jboss.org/browse/JBRULES-2321 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 4.0.7 Reporter: Tihomir Surdilovic Assignee: Mark Proctor This is a problem with Drools 4.0.7, it does not happen in Drools 5: $factB.f1 is triggering a scenario where the engine creates an implicit biding to the "f1" field. That in conjunction with the use of "or" is triggering the problem rule "implicit bindings test" when FactA() $factB : FactB( $fB : f1 ) (not FactC( f1 == $factB.f1 ) or FactC() ) then end The exception thrown is: java.lang.ClassCastException: com.sample.FactAShadowProxy cannot be cast to com.sample.FactB at org.drools.base.com.sample.FactB1865721816$getF1.getIntValue(Unknown Source) at org.drools.base.extractors.BaseIntClassFieldExtractor.getHashCode(BaseIntClassFieldExtractor.java:85) at org.drools.base.ClassFieldExtractor.getHashCode(ClassFieldExtractor.java:225) at org.drools.rule.Declaration.getHashCode(Declaration.java:273) at org.drools.util.AbstractHashTable$SingleIndex.hashCodeOf(AbstractHashTable.java:533) at org.drools.util.TupleIndexHashTable.getOrCreate(TupleIndexHashTable.java:315) at org.drools.util.TupleIndexHashTable.add(TupleIndexHashTable.java:227) at org.drools.reteoo.NotNode.assertTuple(NotNode.java:93) at org.drools.reteoo.CompositeTupleSinkAdapter.propagateAssertTuple(CompositeTupleSinkAdapter.java:30) at org.drools.reteoo.JoinNode.assertObject(JoinNode.java:156) at org.drools.reteoo.SingleObjectSinkAdapter.propagateAssertObject(SingleObjectSinkAdapter.java:22) at org.drools.reteoo.ObjectTypeNode.assertObject(ObjectTypeNode.java:162) at org.drools.reteoo.Rete.assertObject(Rete.java:175) at org.drools.reteoo.ReteooRuleBase.assertObject(ReteooRuleBase.java:192) at org.drools.reteoo.ReteooWorkingMemory.doInsert(ReteooWorkingMemory.java:71) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:911) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:883) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:684)
