According to Drools 5.5 reference doc "Nullable planning variables are not supported for construction heuristics in 5.5.x or lower." I cannot config the planning variable to be null using drools 5.5? -- View this message in context: http://drools.46999.n3.nabble.com/Nullable-Planning-Variable-tp4026757.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

I am using 6.0.0CR5. I configure the planning variable to be null. Now using the construction heuristic <constructionHeuristic> <constructionHeuristicType>FIRST_FIT</constructionHeuristicType> <forager> <pickEarlyType>FIRST_NON_DETERIORATING_SCORE</pickEarlyType> </forager> </constructionHeuristic> all the planning entities was assigned with a planning variable even if the assignment lead to a negative hard constraint. I assumed that some of it will be assigned by null to avoid the negative hard constraint. Is my assumption correct way of using the nullable planning varibale config? Thanks. -- View this message in context: http://drools.46999.n3.nabble.com/Nullable-Planning-Variable-tp4026757p40...
