how do I modify the server that it is comunicating with for development and production migration?
Could you be a bit more specific about what you need to do here?
In the last part of your message you mean that you want to use WS instead of Remote Objects?
I was using web services and I am curious how to, if its possible, to have
strong typing when using web services.
However, I have switched to Remote Objects - the reason for the post was to
understand what needed to be changed when moving an application from a
development server to a production server?
Strong typing is not supported when using CFC's as webservices.
With Flex Remoting, you don't have to change anything when moving the app to a production server.
Just make sure that the services-config.xml and/or remoting-config.xml matches on both servers (that is, if you're using a modified one).
If you're using the default "ColdFusion" endpoint, everything should work "out of the box".
