At the end of the FlashForward Keynote this morning, Kevin ran a video from one of the Macromedia engineers who is working on some new technology (code named Royale) that we are working on. He showed a Flash based input form with multiple sections. He then showed the code used to build it, which was written entirely in XML. Not only was the entire Flash application created from the XML file, but so was all of the databinding (SOAP Based), ActionScript and StyleSheets (yes, Cascading Style Sheets).
I sure hope this is based on the XForms spec. It could go a long way to advancing the usage of XForms in the developer community. If this is a properitary XML format, I'll be pretty disappointed since the XForms spec is pretty complete and lays out just about everything you'd want to do with a Form. With all my work on qForms, I've learned one thing—the current HTML implementation of forms leaves a lot to be desired. I'm still not sure I'm sold on the performance of RIA in Flash, but performance does seem to be getting better.
