The method dataClass() does not exist on SilverStripe\ORM\SS_List. It seems like you code against a sub-type of said class. However, the method does not exist in SilverStripe\ORM\Sortable or SilverStripe\ORM\Filterable or SilverStripe\ORM\Relation or SilverStripe\ORM\Limitable or SilverStripe\ORM\Relation or SilverStripe\ORM\Relation or SilverStripe\ORM\Relation. Are you sure you never get one of those?

The assignment to $proj is dead and can be removed.
