[rules-users] Getting an Error While Executing Rule in Drools 5.0
Hi, I have compiled some rules and added it in packages. Then I serialized those packages and stored in database in the form of CLOB data Now I am able to get Packages back from database and loaded it in RuleBase. But while executing Rule, I am getting the following Exception. java.lang.NullPointerException at org.drools.base.ClassFieldReader.getValue(ClassFieldReader.java:91) at org.drools.base.evaluators.EqualityEvaluatorsDefinition$StringEqualEvaluator.evaluate(EqualityEvaluatorsDefinition.java:1962) at org.drools.rule.LiteralRestriction.isAllowed(LiteralRestriction.java:92) at org.drools.rule.OrCompositeRestriction.isAllowed(OrCompositeRestriction.java:25) at org.drools.rule.MultiRestrictionFieldConstraint.isAllowed(MultiRestrictionFieldConstraint.java:97) 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.reteoo.ReteooStatelessSession.execute(ReteooStatelessSession.java:201) The similar kind of issue is already logged by someone.
