org.springframework.webflow.engine.model.TransitionModel
Model support for transitions.
A path from this state to another state triggered by an event. Transitions may execute one or more actions. All transition actions must execute successfully for the transition itself to complete. If no transition target is specified, the transition acts as a simple event handler and does not change the state of the flow. @author Scott Andrews
