Hi Chris,

Hi All,
I have an inheritance relationship between my Product and Car
objects. New inserts of car objects work fine. The problem I'm experiencing
is that when I remove a car the corresponding product record is not being
removed from the product table. The mappings are shown below. I'm using
version db-ojb-1.0.4, the oscahce for caching, and the remote locking
implementation. Is there something wrong with my mappings? I've included my
stack trace so that you can observe that the car and all the relationships
are removed correctly, but not the product entry. Please advise.
Thank you,
Chris
