AND works in a rule, but OR gives a classCastException ------------------------------------------------------ Key: JBRULES-1205 URL: http://jira.jboss.com/jira/browse/JBRULES-1205 Project: JBoss Rules Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 4.0.1 Environment: Win XP Reporter: Arsalan Zaidi Assigned To: Mark Proctor From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Edson Tirelli Sent: Tuesday, September 18, 2007 6:08 PM To: Rules Users List Subject: Re: [rules-users] Problem in using or operator with values in map. This seems a bug. May I ask you please to open a JIRA for it and attach a self contained test showing the problem? At the same time, I think there is a conceptual error in your rules: no object should be changed in the LHS of the rules. This will surely cause you problems in the future, so, I strongly advise you to rethink your rules. []s Edson 2007/9/18, Gaurav2007 <gaurav.a.joshi(a)capgemini.com&gt;: Hi All, I am using drool 4.0.1,I am facing some problem in using or operator i am using 2 maps by inserting in to working memory: 1) ErrorMap<"String","String"> 2) validationmap<String,Object> my requirment is to generate error when rule fails for this i am taking following steps: 1) i insert one entry in error map in when part and if that rule is success 2)i remove that entry from map and 3) at the end on the basis of this map i generates validation errors. import java.util.Map; import com.IValidationField; rule "ValueAllowed_G10.3" when IValidationField(attributeId =="G10.3") $map : Map( keySet contains "ErrorMap" ) eval($map.put("G10.3_V","E_V_ALLOWED") == null || true) (or Map( this["G10.2"] not in("5")) Map( this["G10.2"] in("5"))) then map.remove("G10.3_V "); System.out.println("comming here----------------------------------------->"); end this file is giving classcast exception org.drools.RuntimeDroolsException: java.lang.ClassCastException : com.ValidationFieldImpl at org.drools.rule.EvalCondition.isAllowed(EvalCondition.java:75) at org.drools.reteoo.EvalConditionNode.assertTuple(EvalConditionNode.java:141) at org.drools.reteoo.SingleTupleSinkAdapter.propagateAssertTuple (SingleTupleSinkAdapter.java:20) at org.drools.reteoo.JoinNode.assertTuple(JoinNode.java:120) but when i replace "or" with "and" operator then it is working fine: import java.util.Map ; import com.IValidationField; rule "ValueAllowed_G10.3" when IValidationField(attributeId =="G10.3") $map : Map( keySet contains "ErrorMap" ) eval($map.put("G10.3_V ","E_V_ALLOWED") == null || true) (and Map( this["G10.2"] not in("5")) Map( this["G10.2"] in("5"))) then map.remove("G10.3_V"); System.out.println ("comming here----------------------------------------->"); end -- View this message in context: http://www.nabble.com/Problem-in-using-or-operator-with-values-in-map.-tf...
