Ordered many-to-many are not currently supported, and I'm not sure how efficient it would be to do it, from a performance point of view. A reorder would result in a lot of updates if keeping the sort indexes in the many-to-many table.
You could maybe use this variant, in which you define the many-to-many relation object yourself: Entity EntityA { String name key - List<@EntityABRelation> relatedTypeBs opposite entityA } ValueObject EntityABRelation { - @EntityA entityA opposite relatedTypeBs - @EntityB entityB opposite relatedTypeAs } Entity EntityB { String name key - List<@EntityABRelation> relatedTypeAs opposite entityB } But, I would suggest another design. Maybe storing the ordered ids as a comma separated string in EntityA and use a Set for the many-to-many association and do the sorting in java. /Patrik greatfooty wrote: > > Guys > > Not sure if this is possible using sculptor but I'm trying to figure > neatest way to do re-ordering of a List of EntityB where it participates > in a many-to-many relationship with EntityA.
