I have a simple 4 entities(tables) structure:

a - columns: id(generated), x

b - columns: id(generated), a_id(fk to a), y

c - columns: id(generated), a_id(fk to a), z

d - columns: id(generated), b_id(fk to b), c_id(fk to c), w

relationships as follows:

a->b one-to-many unidirectional;

a->c one-to-many unidirectional;

b->d one-to-many unidirectional;

c->d one-to-many unidirectional

All relationships cascaded.

hibernate performs incorrect order of inserts when persisting a:

should be a,b,c,d

does: a,b,d and fails without having generated

How can I enforce the correct order?

However I can set b_id and c_id to nullable, but then I ,will have inserts and updates. I would like to avoid it.

Thanks

Mark

Set bi-directional to a-b, a-c and b-d. Saw some improvements but could not get rid of updates.
