BUG: Filter by author does not work
In the main page, when you select an author and filter the map with this point, nothing happens. The following error messages appear in the console:
Backend returned code 400, body was: More than one FilterValue with specified rank.
ERROR An error occured while getting group by reference for hal. Please try again later.
This is the case for all 3 installations; cartolabe.fr, cartolabe-dev.fr, cartolabe-beta.lri.fr.
