org.springframework.webflow.engine.support.TransitionExecutingFlowExecutionExceptionHandler
A flow execution exception handler that maps the occurrence of a specific type of exception to a transition to a new {@link org.springframework.webflow.engine.State}.
The handled {@link FlowExecutionException} will be exposed in flash scope as{@link #FLOW_EXECUTION_EXCEPTION_ATTRIBUTE}. The underlying root cause of that exception will be exposed in flash scope as {@link #ROOT_CAUSE_EXCEPTION_ATTRIBUTE}. @author Keith Donald
