Many-to-one / set

Hi,

I have a problem with Sets. After adding a "slave" record it doesnt always appear in the set. Should I reload the "master" record in order to refresh/ re-read its set? or is there a more efficient way.

Thanks,
Mike Burton.

Using:
Hibernate version:2
with: MySql 5.0.15:

Could you be more specific, is that when you try to persist your data or when your are loading the object back.

I've persisted the data, I can see it in the SQL database.
But I dont see it in my data objects.
eg my main table is master and it has a set of slaves...
aMaster.getSlaves().size() has not been incremented as I would have expected.

I've tried manually doing it,
ie after I persisted by calling DAO.save(aSlave)
I then called aSlave.getMaster().add(aSlave).

Having to do this doesnt seem right somehow, and it doesn't work for the first slave I add for a given master (it only works for subsequent ones).
