[rules-users] eval in lhs

Can i have the following as one of my conditions in decision table ? eval(convertYesOrNo("$param").equals(myObject.getFlag())) where convertYesOrNo() is a function inside decision table. I get the following error - Exception e org.drools.RuntimeDroolsException: Exception executing predicate com.barcap.efg.fine.drools.dataobject.Rule_Corporate_Action_12_0Predicate0Invoker@490d7410 org.drools.RuntimeDroolsException: Exception executing predicate com.barcap.efg.fine.drools.dataobject.Rule_Corporate_Action_12_0Predicate0Invoker@490d7410 at org.drools.rule.PredicateConstraint.isAllowed(PredicateConstraint.java:279) at org.drools.reteoo.AlphaNode.assertObject(AlphaNode.java:143) at org.drools.reteoo.CompositeObjectSinkAdapter.doPropagateAssertObject(CompositeObjectSinkAdapter.java:360) at org.drools.reteoo.CompositeObjectSinkAdapter.propagateAssertObject(CompositeObjectSinkAdapter.java:344) at org.drools.reteoo.ObjectTypeNode.assertObject(ObjectTypeNode.java:185) at org.drools.reteoo.EntryPointNode.assertObject(EntryPointNode.java:146) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:1046) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:1001) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:788) at org.drools.impl.StatefulKnowledgeSessionImpl.insert(StatefulKnowledgeSessionImpl.java:216) at Thanks. -- View this message in context: http://n3.nabble.com/eval-in-lhs-tp112964p112964.html Sent from the Drools - User mailing list archive at Nabble.com.
