|| in conditional element causes exception ------------------------------------------ Key: JBRULES-1558 URL: http://jira.jboss.com/jira/browse/JBRULES-1558 Project: JBoss Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: Reteoo Affects Versions: 4.0.4 Reporter: Juraj Bednar Assigned To: Edson Tirelli Priority: Minor rule "testRule" dialect "mvel" when $m : TestFact ( booleanTest == true && (number <= 100 || number >= (anotherNumber * 2))) then System.out.println("Error"); end ("&&" can be also replaced by "," having the same effect) This rule compiles well and in runtime, when booleanTest becomes true, it creates this Runtime exception: org.drools.RuntimeDroolsException: Exception executing ReturnValue constraint org.drools.rule.ReturnValueRestriction@3f3d9830 : java.lang.ClassCastException: org.drools.rule.AbstractCompositeConstraint$MultiFieldConstraintContextEntry cannot be cast to org.drools.rule.ReturnValueRestriction$ReturnValueContextEntry at org.drools.rule.ReturnValueConstraint.isAllowed(ReturnValueConstraint.java:102) at org.drools.rule.OrConstraint.isAllowed(OrConstraint.java:50) at org.drools.reteoo.AlphaNode.assertObject(AlphaNode.java:137) at org.drools.reteoo.CompositeObjectSinkAdapter.propagateAssertObject(CompositeObjectSinkAdapter.java:318) at org.drools.reteoo.AlphaNode.assertObject(AlphaNode.java:145) at org.drools.reteoo.CompositeObjectSinkAdapter.propagateAssertObject(CompositeObjectSinkAdapter.java:309) at org.drools.reteoo.ObjectTypeNode.assertObject(ObjectTypeNode.java:153) 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:915) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:887) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:688) at spairal.sensors.AbstractSensor.collectData(AbstractSensor.java:60) at spairal.SensorManager$1.run(SensorManager.java:55) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:441) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:287) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:679) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:704) at java.lang.Thread.run(Thread.java:637) Caused by: org.drools.RuntimeDroolsException: java.lang.ClassCastException: org.drools.rule.AbstractCompositeConstraint$MultiFieldConstraintContextEntry cannot be cast to org.drools.rule.ReturnValueRestriction$ReturnValueContextEntry at org.drools.rule.ReturnValueRestriction.isAllowed(ReturnValueRestriction.java:175) at org.drools.rule.ReturnValueConstraint.isAllowed(ReturnValueConstraint.java:96) ... 20 more Caused by: java.lang.ClassCastException: org.drools.rule.AbstractCompositeConstraint$MultiFieldConstraintContextEntry cannot be cast to org.drools.rule.ReturnValueRestriction$ReturnValueContextEntry at org.drools.rule.ReturnValueRestriction.isAllowed(ReturnValueRestriction.java:165) ... 21 more The syntax is OK according to documentation: ----- It is possible to change the evaluation priority by using parenthesis, as in any logic or mathematical expression. Example: Example 6.10. Using parenthesis to change evaluation priority # Cheese type is stilton and ( price is less than 20 or age is mature ). Cheese( type == "stilton" && ( price < 20 || age == "mature" ) ) -----
