If you are trying to debug Flex ColdFusion connectivity issues, then be sure to keep in mind that if you start ColdFusion at the command prompt you’ll see a detailed dump of the messages, both in and out. To do this (on Windows):
- Make sure that ColdFusion is not running.
- Open a command prompt window.
- Go to c:cfusionmx7bin (or the appropriate folder in your own installation).
- Run cfstart.
This one has helped me solve all sorts of problems, from pathing issues to case-sensitivity issues to figuring out exactly what data is being passed as and more.
