    In practice, I've found I always use a simpler version that only retrieves a
    single object. Maybe it would make sense to add a "localObject" method as
    well.

            public static DataObject getLocalObject(DataContext context, DataObject
    obj)
            {
                    if (null == obj) return null;
                    
                    if (obj.getDataContext() != context)
                    {
                            ObjEntity ent =
    context.getEntityResolver().lookupObjEntity(obj.getObjectId().getObjClass());
                            obj = context.objectFromDataRow(ent, obj.getCurrentSnapshot(), true);
                    }
                    return obj;
            }
