Hi Remy, Is there a reason, not to use createAndInsertObject(ec, SubEntity.class) ?
In think, the WO way would be sth like: SubEntiy sub = ERXEOControlUtilities.createAndInsertObject(ec, SubEntity.class); sub.addObjectToBothSidesOfRelationshipWithKey(relation(), "refEntity"); ec.saveChanges(); If you really want to model a polymorphic relationship, the destination of the relationship "refEntity" should be EntityAbstract.

I have an Entity Abstract named "EntityAbstract" and a subclass Entity named "EntitySub" where the qualifier is (refEntityName=‘EntitySub'). I have third Entity named "Relation" that has an relationship with "EntitySub". I have a problem when : EOEditingContext editingContext = ERXEC.newEditingContext(); int relationID = Integer.valueOf(relation().primaryKeyInTransaction()); EntityAbstract entityAbstract = ERXEOControlUtilities.createAndInsertObject(editingContext(), EntityAbstract.class); entityAbstract.setRefEntityName(EntitySub.ENTITY_NAME); entityAbstract.setRefEntityID(relationID); editingContext().saveChanges(); ERXEOControlUtilities.refreshObject(relation()); for (EntityAbstract e : relation().entitySubs()) System.err.println(e); // Print <your.app.model.EntityAbstract How to print <Entity pk:"..."> and not <EntityAbstract pk:"..."> ? I don't want use the class "Entity" for ERXEOControlUtilities.createAndInsertObject Do you have an idea? I tested : eo.invalidateAllObjects(); eo.parentObjectStore().invalidateAllObjects(); eo.rootObjectStore().invalidateAllObjects(); It does not work...
