Simple one-to-many mapping for deletion

sriramn · **Joined:** Thu Nov 30, 2006 11:05 am **Posts:** 5

Hi,

We have 2 entities. ITEM and VARIABLE. An Item can have more than one-variable. The variables will be updated, which means, every time an item.setVariables(List<Variable>) is invoked and session.saveOrUpdate(item) is done, the old variables should be removed and the new ones be inserted.

The configuration we have works for Inserts, but it fails to delete the existing Variables.

We have the @OneToMany (CascadeType.ALL) defined on Item side and @OneToMany defined on Variable side, with the ITEM_ID primary key join column.

Is there any specific configuration to be provided ? Also, if someone can give the exact config and setup for this, it will be helpful.

Thanks,
Sriram

On the Variable side it should be ManyToOne.
