I'm not 100% sure if I get you.
But, the ordering of EntityB is decided by query, or if not specified, the
order in the table.
If you want to re-define the order and then persist it, I guess you need a
column (say, 'ORDER_COLUMN') for the EntityB. Then when shuffling the list,
update the order attribute on the entities and then
EntityAService.update(entityA).
But as I said, I don't know if this is what you want to do.
And no, there is no support for this kind of functionality.
But of course, we have support for building this kind of functionality with
very few line of code :-)
