[rules-users] Planner - Initialized solution & local search

I'm using v5.4. I've built a prototype which uses the constructionHeuristic, and localSearch, as the example does, and am able to run the solver (though it still doesn't do a good job of solving at this point). I've now added customSolverPhase, and set it to use an initializer class which implements CustomSolverPhaseCommand. In my changeWorkingSolution, I call scoreDirector.beforeEntityAdded(), and then set the planning entity's planning variable, and then call afterEntityAdded(). If I leave any entities unadded -- and let the constructionHeuristic (BEST_FIT, etc) do the fitting (which I can verify from the logs)-- I then get this exception: /java.lang.IllegalStateException: Phase localSearch started with an uninitialized Solution. First initialize the Solution. For example, run a phase constructionHeuristic first./ For now, I can update my code to ensure that all of the entities are fitted and bypass the constructionHeuristic, but I'm curious why this error is getting thrown. I did hunt through the source code to look at all the isInitialized() methods, but I haven't yet stepped through to see which one returns false any why. As for turning on TRACE mode, see my http://drools.46999.n3.nabble.com/drools-planner-5-4-0-Final-java-lang-Il... recent post .
