> Using a primary key to retrieve an object via DataObjectUtils and then retrieving a List relationship via that object results in extremely stale (read: blatantly incorrect) results when an object which is subclassed and uses a qualifier (in my case a single column single character) is added or destroyed unless the relationship is modified on the parent object (i.e. the one retrieved via its PK)
> In short: the relationships between two objects and the object cache become corrupt when at least one of them uses a qualifying field unless the relationships are explicitly modified from the retrieving side on both creation and upon deletion.
> I understand that the object cache can become stale, but this is within the same context over and over again and it does not go away, it does not fix itself over time (which would mean a possible race condition)
