[rules-users] Drools Planner : multiple planning entities

[TEddahabi]

I use the 5.4.0.CR1 version and make
ValueRange.excludeUninitializedPlanningEntity on true (as you advised me),
but I'm getting this exception :

*Exception in thread "main" java.lang.IllegalArgumentException: The
planningEntityClass (class
org.drools.planner.examples.cloudbalancing.domain.CloudAssignment) has a
PlanningVariable annotated property (cloudComputer) with
excludeUninitializedPlanningEntity (true), but there is no planning entity
class that extends the variablePropertyType (class
org.drools.planner.examples.cloudbalancing.domain.CloudComputer).

Could you help me please to fix this problem ?
Thank you !!
