 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.

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

2014-01-13 Thread nxv

The problem is the same as reported by abr.  I work with abr on the project
:)  As he could not reproduce the bug, I just removed lines of code as much
as possible to keep only the essentials.  Here is a unit test: 
Drools-after.zip
http://drools.46999.n3.nabble.com/file/n4027676/Drools-after.zip

 This is unlikely to be the same exception that started the initial
 thread, but a problem nevertheless.. :(
 could you create a self-contained test case and submit it?
 Thanks

 That was recreated on 5.6.0.CR1 ? The 5.6 ship has sailed now :( and
 currently there are no plans for 5.7 any time soon. We should focus on
 making sure this is fixed in 6.x.

 Hello,

 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
