Array of object not supported by contains ------------------------------------------ Key: JBRULES-805 URL: http://jira.jboss.com/jira/browse/JBRULES-805 Project: JBoss Rules Issue Type: Bug Security Level: Public(Everyone can see) Environment: linux, java1.4 Reporter: ahmed yehdih Assigned To: Edson Tirelli Original Estimate: 1 hour Remaining Estimate: 1 hour when the array is an array of object like String we get java.lang.ClassCastException at org.drools.base.evaluators.ObjectFactory$ObjectContainsEvaluator.evaluate(ObjectFactory.java:386) at org.drools.rule.LiteralRestriction.isAllowed(LiteralRestriction.java:61) at org.drools.rule.LiteralConstraint.isAllowed(LiteralConstraint.java:82) at org.drools.reteoo.AlphaNode.assertObject(AlphaNode.java:140) at org.drools.reteoo.CompositeObjectSinkAdapter.propagateAssertObject(CompositeObjectSinkAdapter.java:317) at org.drools.reteoo.ObjectTypeNode.assertObject(ObjectTypeNode.java:183) at org.drools.reteoo.Rete.assertObject(Rete.java:121) at org.drools.reteoo.ReteooRuleBase.assertObject(ReteooRuleBase.java:196) at org.drools.reteoo.ReteooWorkingMemory.doAssertObject(ReteooWorkingMemory.java:70) at org.drools.common.AbstractWorkingMemory.assertObject(AbstractWorkingMemory.java:727) at org.drools.common.AbstractWorkingMemory.assertObject(AbstractWorkingMemory.java:551) example: assume we have a class message class Message{ String [] mess; } rule "test" when Message(mess contains "HELLO") then .. end the reason is the test in the org.drools.base.ValueType class else if ( clazz.isAssignableFrom( Object[].class ) ) { return ValueType.ARRAY_TYPE; the test will be satisfied only for array of java.lang.Object and not for others object a simple solution is to modify this test in else if ( clazz.isArray() && clazz.getComponentType() instanceof Object) { return ValueType.ARRAY_TYPE;
