Flex3 发布了
用过FLEX2，感觉不错，跟ＰＨＰ结合较好，数据交换主要是搞XML，让我来看Flex3 有啥新我特性：
Powerful coding tools
Flex Builder 3 is a powerful Eclipse based IDE that includes editors for MXML, ActionScript™, and CSS, as well as syntax coloring, statement completion, code collapse, interactive step-through debugging, and more.
Rich visual layout (Enhanced in Flex Builder 3)
Visually design and preview user interface layout, appearance, and behavior using a rich library of built-in components. Extend the built-in components or create new ones as needed.
New in Flex Builder 3 — Interactively set and preview CSS values on any of your components in Flex Builder Design view.
Interactive data visualization (Enhanced in Flex Builder 3) (Professional edition only)
Create data dashboards and interactive data analysis by simply dragging and dropping a chart type and linking it to a data source using the Flex charting library. Use the powerful new Advanced Datagrid to enable users to explore complex data.
New in Flex Builder 3 — Use the powerful new Advanced Datagrid to enable users to explore complex data. Charts have also been enhanced with new interaction support, a drawing API, and support for multiple axes.
Skinning and styling (Enhanced in Flex Builder 3)
Customize the appearance of an application using CSS and graphical property editors. Quickly set the most commonly used properties and preview the results in Design view.
New in Flex Builder 3 — Design view has also been enhanced to support rendering of skins and styles, allowing designers and developers to update properties and visualize how they affect each skin without needing to rebuild the application.
Integration with Adobe Creative Suite 3 (New in Flex Builder 3)
New Flex Skin Design Extensions for Adobe Flash®, Illustrator®, Photoshop®, and Fireworks® make it fast and easy to import ready-to-use creative assets from Adobe Creative Suite® software directly into Flex Builder 3. Use the new Adobe Flex Component Kit for Flash CS3 Professional to create interactive, animated content in Flash that can then be exported as a Flex component.
Code refactoring (New in Flex Builder 3)
The new Flex Builder 3 refactoring engine allows developers to quickly navigate through code or restructure code by renaming all references to a class, method, or variable.
Native support for Adobe AIR (New in Flex Builder 3)
Flex Builder 3 provides the fastest way to create applications for the Adobe AIR™ runtime, including all the tools required to build, debug, package, and sign Adobe AIR applications. Adobe AIR lets you quickly develop RIAs for the desktop using the same skills and codebase you use to build RIAs for the browser.
Powerful testing tools (New in Flex Builder 3) (Professional edition only)
The Flex Builder 3 memory and performance profilers enable developers to improve application performance by providing tools to monitor and analyze memory consumption and CPU cycles. Support for automated functional testing tools such as HP QuickTest Professional (formerly Mercury QuickTest Professional) is also now available in Flex Builder 3 Professional.
Advanced data services (New in Flex Builder 3)
Invoke web services or request XML or other data via HTTP using a rich, built-in library of data access services. Use open source BlazeDS to easily connect applications to back-end services leveraging Flex Remoting and Messaging, providing binary, high-performance, HTTP-based data transport plus real-time data push and pub/sub messaging.
Flex 2 and 3 SDK support (New in Flex Builder 3)
Flex Builder 3 can create applications based on either the Flex 2 SDK or the Flex 3 SDK, enabling developers to leverage many of the great new Flex Builder 3 capabilities while maintaining Flex 2 applications.
Improved project workflows (New in Flex Builder 3)
Use new Flex Builder 3 project wizards to support the most common back ends. New wizards make it fast and easy to get started, whether you're using Adobe ColdFusion®, PHP, ASP.NET, or Java™. Workflow for developers using Adobe LiveCycle® Data Services is improved as well, and improved project portability support enables developers to share projects and application settings more easily.
Web service introspection (New in Flex Builder 3)
Flex Builder 3 can now retrieve a WSDL and generate ActionScript proxies to make calls and serialize/deserialize strongly typed objects. New code hinting is available for making web service calls and dealing with responses.
