Re: [rules-users] Drools Planner: Planning variable gets assigned value out of valueRange => primitive types problem

Yes, FROM_PLANNING_ENTITY_PROPERTY works in 5.4.0.Final. You're suffering from a different problem: Change your planning variable type from long to Long and default it null. Planner presumes that a variable == null is uninitialized, but a variable == 0 it considers initialized. As a result, the construction heuristic won't bother to initialize the variables that are == 0. The local search heuristic will change it, but there's no guarantee it won't change all of them. For Planner 6.0, there will be @PlanningVariable(uninitializedEntityFilter = ...), which will make it easy to tell Planner that 0 means uninitialized. Op 30-11-12 10:00, mr_moe schreef:
