Hi Don, it's been ages since I've used DisplayGroups, but it does seem like you're missing an invocation of qualifyDisplayGroup() (if you want to filter objects already in the DG) or qualifyDataSource() (to perform an entirely new fetch) on the DG to actually do anything with the qualifier you've set.
