For some reason the extensions of MAElementDescription where both in SortFunctions-Core and SortFunctions-Magritte. Also the dependency to Magritte in the Metacello config was wrong. Now it works as expected (please test :)). And a new stable version was uploaded to the smalltalkhub repo. Please notice my port includes the option to collate the undefined elements at the beginning or the end, in a similar fashion to ORDER BY [column] NULLS [LAST|FIRST] in SQL (Oracle/PostgreSQL at least). I would also vote to have this in the base image. It is my base image at least :) Regards! -- Esteban A. Maringolo
