    Hi Gary

    Prefetching a select query which should meet your requirements:
    SelectQuery sq = new SelectQuery(Category.class);
    sq.addPrefetch(Category.PRODUCTS_PROPERTY);
    sq.addPrefetch(Category.PRODUCTS_PROPERTY+"."+Product.ORDERS_PROPERTY);
    context.performQuery(sq);

    All best
