OptaPlanner : ValueSelector can not use ValueRangeType.FROM_PLANNING_ENTITY_PROPERTY

I am using MoveSelector configuration in the ConstructionHeuristic Phase. It works fine with configuring filterClass and comparatorClass in EntitySelector.

However, in ValueSelector session, I am not able to use "ValueRangeType.FROM_PLANNING_ENTITY_PROPERTY" planning variable. It throws this exception: java.lang.IllegalArgumentException: The valueSelectorConfig (ValueSelectorConfig(row)) with resolvedCacheType (PHASE) and resolvedSelectionOrder (SORTED) needs to be based on a EntityIndependentValueSelector (FromEntityPropertyValueSelector(row)). Check your @ValueRangeProvider annotations.

Example NQueen Config: ...

<changeMoveSelector>
    <entitySelector mimicSelectorRef="placerEntitySelector">
    </entitySelector>
    <valueSelector>
       <variableName>row</variableName>
       <cacheType>PHASE</cacheType>
       <selectionOrder>SORTED</selectionOrder>
       <sorterComparatorClass>..RowWeightStrength</sorterComparatorClass>
    </valueSelector>
</changeMoveSelector>

....

** I need to use the valueRange depends on my planning Entity in order to use PossibleRowList for each Queen (for the performance sake) Any suggestion please? Thanks in advance.

That valueSelector is SORTED, so it needs to cache (to be able to sort them). But caching with a @ValueRangeProvider per entity is not supported if I recall correctly.

This implies that the CH with a @ValueRangeProvider per entity only supports FIRST_FIT and FIRST_FIT_DECREASING, but not WEAKEST_FIT or STRONGEST_FIT. I believe there's a jira for this already (do link it here if you find it). We need to fix this.

Meanwhile: a workaround would be to not use SORTED, but already sort them in each entity's value range list.
