Most style configuration works fine, where you can have a single style: {:style :ns-justify}, or a series of styles: {:style [:community :respect-bl]}. The problems that occur are when a style itself also specifies a style which is a series of styles. Things seem to break down, and some of the styles don't get handled properly and styles that don't exist don't turn into errors either. I expect this will be fixed in the next release, probably called 1.2.2.
