Access String resource from Barrel within the Barrel code

I have a simple Monkey Barrell called "CompactLib". I don't seem to be able to access string resources from the barrel itself using:

WatchUi.loadResource(CompactLib.Rez.Strings.progress);

I keep getting this error:

Is there some difference between resources in an generic app and barrel? I can see the string in the .prg.debug.xml file...
