[rules-users] OptaPlanner: unsolved score & constraint failure messages

Hi, I have some experience with drools 5 and now experimenting on planner & drools 6. I have 'unsolved' PlanningSolution that could be given to a solver and it successfully solves it. (its just the curriculum example with few more variables like teachingAssistant, equipment etc) I need to know few things about this unsolved solution. 1) I want to know the score of this unsolved before starting to solve it. can I do this without instantiating my own drools session with my score holder and execute the rules for score? i.e only using optaplanner-api and not depend on underlying rules engine used by planner. 2) I also want to have some information on what all rules got fired in calculation of score (the negative ones). to print the conflicting planning entities & their variables. I could put a message from each rule to some object in workingMem. but how can I get those objects back after the solver is done but didnt have a feasible solution/ or even for any given solution. or is there any better way? -- Regards, Sandeep Bandela.
