Our flex project, which works fine in its current environment with coldfusion 7 single server.
We moved this project to Coldfusion 8 multi server, and updated the remoteobject paths relative to the web root.
The error we now receive is
faultCode:Server.Processing faultString:'Unable to invoke CFC - Could not find the ColdFusion Component or Interface myProject.cf.main.' faultDetail:'For details, turn on Robust Exception Information in the ColdFusion Administrator'
The path to the cfc's from the webroot is is myProject/cf/main.cfc ... any ideas?
See my solution here. That solution solves this too.
