Hi,
I've got Article object with many_many relation on Review (relation name: Reviews) object, Keyword (Keywords) and Author (Authors, class extends Member). I've also sortable_many_many relation:
SortableDataObject::add_sortable_many_many_relation('Article','Authors');
SortableDataObject::add_sortable_many_many_relation('Article','Keywords');
But, I don't have sortable many_many extension on Article->Reviews relation. Problem now comes when I try to add new Review for an Article in CMS. I get error from title of thread: Unknown column 'MMSort' in 'order clause'
Any ideas how to fix this?
