Hello, First of all, I'd like to thank all the people involved in making this tool such a great one (this includes whoever writes the reference manual as well). I've been having some problems when comparing BigDecimals (using the compareTo method). I didn't find this issue in any previous post or in Drools' JIRA. However, I've been using Drools for a short time, so I hope you people can help me. The problem: Firing this (simple) rule: rule "Test Rule" when $dec : java.math.BigDecimal() from java.math.BigDecimal.TEN; eval( $dec.compareTo(java.math.BigDecimal.ONE) > 0 ) then System.out.println("OK!"); end Fires this exception: org.drools.RuntimeDroolsException: java.lang.ClassCastException: java.lang.Integer cannot be cast to java.math.BigDecimal at org.drools.rule.EvalCondition.isAllowed(EvalCondition.java:76) at org.drools.reteoo.EvalConditionNode.assertTuple(EvalConditionNode.java:145) at org.drools.reteoo.SingleTupleSinkAdapter.propagateAssertTuple( SingleTupleSinkAdapter.java:20) at org.drools.reteoo.FromNode.assertTuple(FromNode.java:90) at org.drools.reteoo.SingleTupleSinkAdapter.createAndPropagateAssertTuple( SingleTupleSinkAdapter.java:55) at org.drools.reteoo.LeftInputAdapterNode.assertObject( LeftInputAdapterNode.java:116) at org.drools.reteoo.SingleObjectSinkAdapter.propagateAssertObject( SingleObjectSinkAdapter.java:22) at org.drools.reteoo.ObjectTypeNode.assertObject(ObjectTypeNode.java:153) at org.drools.reteoo.Rete.assertObject(Rete.java:175) at org.drools.reteoo.ReteooRuleBase.assertObject(ReteooRuleBase.java:192) at org.drools.reteoo.ReteooWorkingMemory$WorkingMemoryReteAssertAction.execute (ReteooWorkingMemory.java:179) at org.drools.common.AbstractWorkingMemory.executeQueuedActions( AbstractWorkingMemory.java:1315) at org.drools.common.AbstractWorkingMemory.fireAllRules( AbstractWorkingMemory.java:462) at org.drools.common.AbstractWorkingMemory.fireAllRules( AbstractWorkingMemory.java:433) at com.sample.DroolsTest.main(DroolsTest.java:33) Caused by: java.lang.ClassCastException: java.lang.Integer cannot be cast to java.math.BigDecimal at com.sample.Rule_Test_Rule_0Eval0Invoker.evaluate(Rule_Test_Rule_0Eval0Invoker.java:12) at org.drools.rule.EvalCondition.isAllowed(EvalCondition.java:72) ... 14 more I've reported the issue in JIRA ( http://jira.jboss.com/jira/browse/JBRULES-1433) Best regards, José _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
