Simple form controls may feature only one view and one set of data. Easy right? However, many of our real applications are much more complex than mere forms. Managing multiple visual states and sets of data can become overwhelming during the design and development of more robust projects.

With proper design methodologies and development practices we can successfully manage state in our applications. Learn state management to build more powerful applications with greater scalability. While the examples shown will be specific to Flex 3 for deployment to the browser, this session is equally relevant for application developers of other technologies, including Adobe Flash CS3 and Adobe Flex 3 for Adobe AIR desktop deployment.
