When the concept of Rich Internet Applications was formally introduced, it required developers to start thinking about the web a little differently. RIA's are capable of providing a much smoother user experience, but there are other design changes that we must consider as well....beyond the user interface.
One of the most obvious differences between traditional, page-based web applications and RIA's is that page-based apps generally require page refreshes, while Flex applications don't. This presents new challenges for web developers who have just started building Flex applications. Developers are now forced to change the way they think about the view state.
