> When I change JPOX to check for foreign-key constraints and when deleting an object with a FK present to just leave it to the DB to decide what to do (based on the specified FK) the DB throws exceptions. Such as

> The deletion of objects should be handled by the TCK or better defined.
> Alternatively the JDO2 spec should define what a JDO impl ought to do when deletePersistent is called and the object has references to other objects via FKs. JPOX has been nulling these out until now ... so the TCK ran ok. Now that we want to rely on th
e DB FKs we find this issue so would like to know what is "expected behaviour"
