Re: [rules-users] Knowing which constraints are broken for final best solution in drools-planner

Hi geoffrey, thanks for your reply. I followed examples from the older versions (pre 5.4.0.beta2 i guess), using the solvers WorkingMemory. After the *solver.solve()* method returns, calling *workingMemory.iterateObjects()* will return no objects of type *IntConstraintOccurrence*. Is this expected? While the solver is solving, I can obtain this objects and inpect the score inside the *bestSolutionChanged* callback, but afterwards, I only get the problem facts and my planning entities. I'm really confused with what is happening as I don't fully understand how the solver operates the working memory, but is it possible that after solving the score isn't calculated any more, generating no new *IntConstraintOccurrence* after solver has finished solving? Thanks a bunch! Manuel ps. to make myself clear, if I run *workingMemory.iterateObjects()* while it's solving I get this types of objects: ar.edu.itba.epa.core.domain.io.Materia ar.edu.itba.epa.core.domain.solver.facts.ConflictoAlumnosMateria ar.edu.itba.epa.core.domain.io.Horario ar.edu.itba.epa.core.domain.solver.facts.CorrelatividadMateria *org.drools.planner.core.score.constraint.IntConstraintOccurrence* ar.edu.itba.epa.core.domain.Examen ar.edu.itba.epa.core.domain.io.Aula and afterwards I only get: ar.edu.itba.epa.core.domain.io.Materia ar.edu.itba.epa.core.domain.solver.facts.ConflictoAlumnosMateria ar.edu.itba.epa.core.domain.io.Horario ar.edu.itba.epa.core.domain.solver.facts.CorrelatividadMateria ar.edu.itba.epa.core.domain.Examen ar.edu.itba.epa.core.domain.io.Aula -- View this message in context: http://drools.46999.n3.nabble.com/rules-users-Knowing-which-constraints-a...
