org.springframework.webflow.engine.ActionState
A transitionable state that executes one or more actions when entered. When the action(s) are executed this state responds to their result(s) to decide what state to transition to next.
If more than one action is configured they are executed in an ordered chain until one returns a result event that matches a state transition out of this state. This is a form of the Chain of Responsibility (CoR) pattern.
The result of an action's execution is typically the criteria for a transition out of this state. Additional information in the current {@link RequestContext} may also be tested as part of custom transitional criteria,allowing for sophisticated transition expressions that reason on contextual state. @see org.springframework.webflow.execution.Action @author Keith Donald @author Erwin Vervaet
