We have a collection mapped as a Map to a table that has a surrogate key. In our mapping we specify a key, index and a composite-element.

Our issue is that the surrogate key in this table never gets updated in the mapped table.

Question:

1. Should we foregoe the surrogate key here?

2. Is there a way for the mapped table, which is not a Hibernate entity to have its synthetic key assigned automatically when doing an insert?

Could we use idbag in this case for our mapped Map non-entity?

idbag is most likely the way to go.
