Chained Property Path in ShadowSources

[kazaferovic]

Hi. I'm struggling to understand when or for which entity the supplier method of DSV is triggered.
Given a VRP with PlanningListVariable and an additional genuine PlanningVariable on the Visit class:

public class Visit {

    @PlanningId
    private String id;

    @PlanningVariable
    private DisposalPlant disposalPlant;

    @InverseRelationShadowVariable(sourceVariableName = "visits")
    private Vehicle vehicle;

    @PreviousElementShadowVariable(sourceVariableName = "visits")
    private Visit previousVisit;

    @ShadowVariable(supplierName = "previousDisposalPlantSupplier")
    private String previousDisposalPlant;

    @ShadowSources({
        "previousVisit",
        "previousVisit.disposalPlant"
    })
    private String previousDisposalPlantSupplier() {
        if (previousVisit == null)
            return null;
        else
            return previousVisit.getDisposalPlant().getId();
    }
}

Now e.g. when we have Visit-1 with Visit-0 as its previousVisit and then the disposalPlant for Visit-0 is changed, I would expect that previousDisposalPlantSupplier of Visit-1 would be called but it is only the one of Visit-0.
Where is my misunderstanding?

It a bug; DSV where added before mixing @PlanningListVariable and @PlanningVariable was supported, which resulted in an optimization being incorrect when using a mixed model.

Created issue #1948 to track.

The fix was merged and will be released early next month.
Thanks for reporting, @kazaferovic!
