Class FaultPropagation

java.lang.Object

org.flowable.cmmn.engine.impl.util.FaultPropagation

public class FaultPropagation
extends Object

Handles propagation of a BusinessError during CMMN plan item execution.

1. Check if any plan item in the case has a fault sentry on the faulting task (in a catchable state)
2. If found: fail the task, sentries fire naturally via the standard sentry evaluation. Done.
3. If not found: propagate to parent engine via callback (async) or re-throw (synchronous/no parent)

This respects CMMN semantics — sentries can reference plan items across stages, so there is no need to walk the stage hierarchy level by level.

propagateFault

public static void propagateFault(BusinessError fault,
 CommandContext commandContext,
 PlanItemInstanceEntity planItemInstanceEntity)

isFaultCaught

public static boolean isFaultCaught(PlanItemInstanceEntity faultedPlanItemInstance)

Checks if any plan item in the case has a fault sentry referencing the faulting plan item, using the parser-built dependency graph (PlanItem.getEntryDependentPlanItems()). Also verifies that at least one runtime instance of the dependent plan item is in a catchable state (AVAILABLE or WAITING_FOR_REPETITION).
