I am having problems with the following example using php/mysql:
When uploaded on my server, it gives the dreaded "Security Error Accessing URL" message. I put the crossover.xml file in my root, but it doesn't work. I'm still learning, and haven't quite caught up with all the best practices in Flex. When I created my project, I said that it had no server type, and then to deploy on my web server, I am simply exporting as a release build and copying files. Is this poor practice and possibly the reason for this error? What is best practice? The php file works with a simple HTML site, so I know the code is working and the database is set up properly. Can someone please help me out?
Try adding --use-network=true to your compiler options.
In Flex Builder, in menubar:
Project - Properties
Additional compiler options
Often when we develop our apps this does not matter, but when posting online you need it set to true.
