We are pleased to
announce a preview release of Spring Web Flow for use with the Spring
1.2 release path. With this release, we consider the web flow
system fit for development use.
Contained in this release are new features we expect to take web

page flows of
your application as self-contained modules reusable in multiple
- The ability to nest flows ‘n’ levels
subflows), where each flow is a "black-box" adhering to a well-defined
contract for input/output.
- The ability to express page flows
with a pluggable flow definition format (currently Java-based and
XML-based builder formats are provided.)
- The ability to affect the path
through a flow in a
dynamic fashion by reasoning on contextual data in any supported scope.
- The ability to track and respond to
of a page flow.
- Automatic state management with the
store model data in several scopes (event, request, flow)

- An expired flow detector, for automatic cleanup of abandoned flows.
- Out of the box helper actions for
form data binding
- Out of the box Struts 1.x
- Out of the box Spring MVC
- Designed for extensibility, with
plug-in points for customization (custom state types, custom flow
