I’m at MAX2007, sitting in Andre Dragomir’s session, Integrating Flex with Ajax and the Browser. He was demoing an Adobe library that you can insert into an Flex application, a Flex component, or even an empty SWF file to expose it to scripting in the browser. Nice!
This allows developers to access the methods an properties of the Flex app with Java Script. This has huge positive implications for our ability to integrate Flex widgets into both FileMaker via the web viewer and PHP applications delivered on a browser.
A FABridge wizard is built into Flex Builder 3.
The presenter also demonstrated deep linking using JS (unfortunately this JS differs from browser to browser). His example uses parameters after a hashmark, so the browser doesn’t refresh.
