Thanks to everyone who stuck out the preso on Flash Builder for Dreamweaver CS5 users. Clearly this isn’t my month for demos. I’ve uploaded the slides as well as the (working) source code. There are two directories, the Flex directory which includes the source code for the Flex projects and the html directory which includes the HTML code.
It’s got examples for using ExternalInterface, the Flex/AJAX Bridge, and FlashVars. You can grab it here.
