Update score after field update

[Patrick Ondreovici]

Hi,

I have updated a normal field from a planning entity with ProblemChange, but the score remains the same. How can i update the score, after a problemChange ?

Hello,

to update a normal field (not a planning variable field) of a planning entity, use the ProblemChangeDirector#changeProblemProperty [1] in your ProblemChange implementation. The next solution OptaPlanner will produce contains this change and the score is updated accordingly.

If that's not the case, please share your ProblemChange implementation, perhaps via StackOverflow (syntax highlighting helps) [2].
