public class FlowExecutionException
extends FlowException

Base class for exceptions that occur within a flow while it is executing. Can be used directly, but you are encouraged to create a specific subclass for a particular use case.

Execution exceptions occur at runtime when the flow is executing requests on behalf of a client. They signal that an execution problem occurred: e.g. action execution failed or no transition matched the current request context.
