Hello Guys,
I'm new to Drools/Planner, I working into a Proof of Concept using Planner to solve
Boat arrival scheduling on Port Management System.
Following JBoss Planner documentation:
- A model was defined: br.gov.serpro.sunac.psp.pes.bean
- A score function: HARD_AND_SOFT
- Rule was created: AgendamentoEmBerco.drl
- Solver was initialized.
Two tests were implemented:
- AgendamentoTest simple rule test with no solver. Works fine.
- ProgramacaoEletronicaSolutionTest test same rule with solver support.
So, when runnig the ProgramacaoEletronicaSolutionTest I've got a Exception
Exception executing consequence for rule "Agendamento com colisao de horário para o
berço" in br.gov.serpro.sunac.psp.pes.rules: java.lang.NullPointerException

Geoffrey De Smet resolved JBRULES-3424.
---------------------------------------
Resolution: Rejected
As the exception message says, the "then" part of that rule has a NPE.
Looking at the drl, it's clear that
global java.util.List resultado
is probably still null at that time.
This issue has therefor been rejected.
There's a different issue to allow using globals in Planner: JBRULES-3329.
"Exception executing consequence for rule" caused by NPE

Key: JBRULES-3424
URL: https://issues.jboss.org/browse/JBRULES-3424
Project: Drools
Issue Type: Bug
Security Level: Public(Everyone can see)

Affects Versions: 5.3.0.Final
Environment: Eclipse 3.6.2

Hello Guys,
I'm new to Drools/Planner, I working into a Proof of Concept using Planner to create
a feature that solve ship arrival scheduling for our Port Management System.
Following JBoss Planner documentation:
- A model was defined: br.gov.serpro.sunac.psp.pes.bean
- A score function: HARD_AND_SOFT
- Rule was created: AgendamentoEmBerco.drl
- Solver was initialized.
Two tests were implemented:
- AgendamentoTest simple rule test with no solver. Works fine.
- ProgramacaoEletronicaSolutionTest test same rule with solver support.
So, when runnig the ProgramacaoEletronicaSolutionTest I've got a Exception
Exception executing consequence for rule "Agendamento com colisao de horário para o
berço" in br.gov.serpro.sunac.psp.pes.rules: java.lang.NullPointerException
