Here is my entire roles file. Some of the data source entries came from
the ECM days I believe (which I'm not using anymore) and I forgot where I
got the other examples from, but at the moment they are all commented out.
I've tried changing the shorthand names, hints, etc. and nothing helped
unfortunately.
Just for completion sake I've included the config snippet that calls out
the datasource below the roles list.
Thanks a bunch,
Robert

This is usually something to do with the meta data or roles file. I
assume
you're looking up the service via something like:
serviceManager.lookup(DataSourceComponent.ROLE);
Can you post one of your role files?
