[rules-users] SimpleScoreCalculator

Hello, since i'm not moving a step from where I am at dsl rule, I'm trying to do it with SimpleScoreCalculator, but the same is happening. ------------ public HardAndSoftScore calculateScore(Distributor distributor) { int hardScore = 0; int softScore = 0; for (Engineer e : distributor.getEngineerList()){ long skill = e.getSkillEngineerList().get(0).getSkill().getId(); int requiredWorktime = 0; long requiredSkill = 0l; for (WorkOrder o : distributor.getWorkOrderList()){ if (e.equals(o.getEngineer())){ requiredWorktime += o.getRequiredWorktime(); requiredSkill = o.getRequiredSkills().get(0).getSkill().getId(); } } int engineerAvailableTime = e.getWorktime() - requiredWorktime; if (engineerAvailableTime < 0 ){ hardScore += engineerAvailableTime; } if (requiredSkill == skill){ softScore += requiredSkill; } } return DefaultHardAndSoftScore.valueOf(hardScore, softScore); } ------------ wouldn't that have to fit since i'm comparing the 1st attribute of each skill list from engineers and workorders? And how can I weight which engineer would be better to a determined workorder if the workorder have more skills and so does the engineer?
