Hi - I found that this error occurs frequently when moving a Flex project from one machine to another.
In my situation, I am exporting a release build so another developer can run it on their machine; they don't have Flex, only the flash player to run it. They are receiving this error and the source is a RemoteObject call that points to a service on their machine. So, do I check the web.xml file for their machine? Or the services-config.xml on their machine? I just don't know where to start. Any tips are, of course, very much appreciated. Happy Thanksgiving. Thank you.
