I am working on my first Drupal/Flex integration project. So far I have been really impressed with the Flex Builder, and the thought that has gone into ActionScript3 and MXML.
My first useful tip has been how to get Flex to talk to Firebug: http://labs.findsubstance.com/2008/02/26/firebugs-console-log-flash-debugging-made-easy/
Just: import flash.external.ExternalInterface;
and then call: ExternalInterface.call( "console.log" , "Hey! I'm tracing from Flash!");
Super easy.
Yup
Glad you're diggin' Flex with Drupal.
