Cascade Delete on 3 Entities not working

ppc Feb 10, 2006 8:23 AM

I've 3 Entities

A have a @OneToMany (cascade = CascadeType.ALL,...) with B
B have a @OneToMany (cascade = CascadeType.ALL,...) with C

If I create A and B
then i can delete A (B is also deleted)

if I create B and C
then I delete B (C is also deleted)

but:

if I Create A, B and C
then
I got and org.hibernate.exception.ConstraintViolationException on B
when I try to delete A

in the logs seam that hibernate is not considering that B has also a cascade delete.

That 's most likely something else. The example you describe works

I've got a similar issue.
For some odd reason, if I use a detached object and pass it back to the server to delete the object, it works fine. If I just pass the id of the object and have the server do a lookup then remove on the object, I get the same errors you are describing.

---------------------------------- Works ---------------------

Detached Client

Company company = proxy.findMyCompany();
proxy.delete(company)

Server

persistenceManager.remove(company);

--------------------------------------------- Doesn't work --------------------------------------

Detached Client

proxy.deleteCompany(companyId);

Server

Company company = persistenceManager.find(compan);
persistenceManager.remove(company);
