------------------------------------------
Description:
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
