I have a planning entity which has a "ResourceType" on it and I am attempting to schedule resources on the entity. The Resource is the Planning variable and the Resource instance has a "ResourceType" on it as well. I want to filter to make sure that a ResourceType matches between the PlanningEntity and the PlanningVariable prior to subjecting it to rules (since this is a hard constraint that can never be broken and want to save on performance). For example, if my PlanningEntity calls for a resource of type "janitor", then I shouldn't assign a Resource (PlanningVariable) of type "teacher" to the event. In order to filter these, I implemented a SelectionFilter class and validate that the entity's resource type matches the planning variable's resource type and return false if not. This is definitely returning the correct values (I debugged this to confirm), but yet my final solution is still getting the wrong resource types on it. My implementation for my filter: public boolean accept(ScoreDirector scoreDirector, PlanningEvent selection) { return selection.getRequiredResourceType().getType() .equals(selection.getResource().getResourceType().getType()); } My configuration: <changeMoveSelector> <entitySelector> <entityFilterClass> com.lmco.mst.lss.autoscheduler.domain.move.RequiredTypeEntityFilter </entityFilterClass> </entitySelector> </changeMoveSelector> Please advise, I am kind of stuck. Thanks!
