[rules-users] 5.6.0.CR1 gives a NullPointerException in after evaluator

Hi everyone, I tried to switch from 5.5.0.Final to 5.6.0.CR1 and got a null pointer exception in the evaluation of the after evaluator. (Exact method is: /org.drools.base.evaluators.AfterEvaluatorDefinition.AfterEvaluator.evaluate(InternalWorkingMemory, InternalReadAccessor, InternalFactHandle, InternalReadAccessor, InternalFactHandle)/ ) When debugging, the exception occurs at the very first line of the method, in: / if ( extractor1.isNullValue( workingMemory, handle1.getObject() ) || extractor2.isNullValue( workingMemory, handle2.getObject() ) ) { return false; } / The cause of the exception is that handle1 is null. The rule where the exception occurs looks like: / MyFact( fromdate before[ 0d ] $min, ( todate == null || todate after[ 0d ] $max ) ) / When the exception occurs, /MyFact.fromdate/ is not null, /$min/ is not null, /MyFact.todate/ is null, /$max/ is not null. In AfterEvaluator.evaluate : /extractor1/ refers to /MyFact.todate/, /extractor2/ refers to /$max/, /handle1/ is null, /handle2/ refers to the fact including the attribute to which /$max/ variable is bound to. Of course, this worked fine in 5.5.0.Final. I couldn't test this out in Drools 6.0.0.CR5 because I have dependencies to drools-spring JAR that does not exist anymore in 6.0.0.CR5. Is it simple to fix this problem? Thanks in advance. Best, Alexis -- View this message in context: http://drools.46999.n3.nabble.com/5-6-0-CR1-gives-a-NullPointerException-...
