Hi David,
Is anything specific updated in the other futureprices (when you insert a new one)? I see that you have indexed on
false, so it is not the index field which is changed.
Teneo also supports most of the hibernate specific annotation set:
http://www.hibernate.org/hib_docs/annotations/reference/en/h tml_single/
One of them is the Cascade, so I think you should have something like this:
@Cascade( { DELETE_ORPHAN, REMOVE } )
you can keep the cascade in the OneToMany, the @Cascade annotation takes precedence.
