===============================

|
||||
Changes in version 2.0 RC1 (11.04.2008)
|
||||
-------------------------------------
|
||||
Major New Features
|
||||
* Introduced a new Web Flow 2 reference guide, available in PDF and HTML format. The new guide is written in "quick reference" style with complete code examples.
|
||||
|
||||
* Added support for migrating from Web Flow 1 to 2. Included in this distribution is a WebFlowUpgrader tool capable of converting flows from the version 1 syntax to the version 2 syntax.
|
||||
See the reference guide for instructions on how to use this tool.
|
||||
|
||||
* Added support for flow definition inheritance. With this feature, A flow may extend one or more flows. A flow state can also extend another state.
|
||||
This feature is used to facilitate reuse between flows and states that share a common structure.
|
||||
|
||||
* Added Portlet support. See the Portlet section of the reference guide and the booking-mvc-portlet and booking-faces-portlet sample applications for examples.
|
||||
|
||||
* Introduced the spring-js module called "Spring Javascript".
|
||||
This module provides a Javascript abstraction framework for applying client-side behaviors such as form validation and Ajax in a consistent manner.
|
||||
The default UI toolkit this framework builds upon is Dojo 1.
|
||||
Spring's JSF integration module called "Spring Faces" builds on spring-js to provide simple declarative JSF components for validation and Ajax.
|
||||
|
||||
* Added integration with the RichFaces JSF component library. Rich Faces can be used with the Spring Faces component library or used standalone.
|
||||
|
||||
* Added a "jsf-booking" reference application that offers a comparsion between a traditional "JSF-centric" web application and a Spring web application that uses JSF as the UI component model.
|
||||
Compare jsf-booking with booking-faces to see the differences in the architectural approach and implementation. Particularly insightful for seasoned JSF developers interested in Spring.
|
||||
|
||||
* Introduced support for automatic model binding and validation with Spring MVC. This support provides a concise alternative to manual setupForm and bindAndValidate calls using FormAction.
|
||||
This support also allows registration of data input Formatters application wide, reducing the need to manually register PropertyEditors on a view-by-view basis in many cases.
|
||||
Support for suppressing data binding for a event such as a cancel button click is also provided.
|
||||
|
||||
* Introduced view scope. View scope is allocated when a view-state enters and destroyed when a view-state exits. The scope is particularly useful for updating a model over a series of Ajax requests.
|
||||
|
||||
* Added support for flow message bundles. Create a messages.properties file in your flow's working directory for the Locales you need to support and off you go.
|
||||
|
||||
* Introduced configurable view-state history polices. A view state can preserve its history to support backtracking, discard its history to prevent backtracking, and invalidate all previous history
|
||||
to disallow backtracking after a point of no return. See the new 'history' attribute on the view-state element.
|
||||
|
||||
* Refined the flow execution snapshotting process. These refinements capture view-state form values on postback to support restoring those values when backtracking.
|
||||
|
||||
* Simplified flow execution testing by allowing you to "jump" to any state to begin a test case. See the booking-mvc and booking-faces for examples of flow test cases.
|
||||
|
||||
Minor Improvements
|
||||
* Added "before view rendering" and "after view rendering" FlowExecutionListener callbacks.
|
||||
* Upgraded to Dojo 1.1 from 1.0.
|
||||
* Attempts to lock a Conversation will now throw an Exception after a configurable timeout period (default is 30).
|
||||
* Changed the faces-config schema to simply 'faces' in-line with Spring conventions.
|
||||
* Added automatic registration of all Spring 2 Flow scopes in the flow-local application context, removing the need for a custom enable-flow-scopes tag.
|
||||
* Added a flow-registry 'parent' attribute, allowing registries to be linked together in a hierarchy.
|
||||
* Made the JSF 1.2 RI the default JSF implementation used by the JSF samples.
|
||||
* Updated the distribution structure to use the new "Spring Build" system.
|
||||
* Made backport-util-concurrent the fallback concurrency framework in a Java 1.4 environment, instead of oswego-concurrent.
|
||||
* Added a dynamic subflow resolution capability.
|
||||
* Simplified the FlowHandler interface and added examples of implementing FlowHandlers to manage access to a flow in a custom manner.
|
||||
* Upgraded the booking-mvc sample to show a mixing Spring MVC @Controllers with web flows, which is typical in a real-world application.
|
||||
* Added ExternalContext.getLocale() to get the client locale from the flow in a portable manner.
|
||||
* Added ExternalContext.getCurrentUser() to get the current user principal from the flow in a portable manner.
|
||||
* Restored support for setting action execution attributes such as validatorMethod. See the <attribute> sub-element of <evaluate>, <set>, and <render>.
