Manage patch operations into OneToMany relations (JPA context)

[pdorgambide]

Hi:
We have a web app were use the sugested JpaPersistenceCallback, and have a model where exist a parent entity with many items (OneToMany JPA hibernate context). At client side we want work only with the parent reference (single shadow) change properties and adding and remove items:

{"op":"add","path":"/items/0","value":{"name":"Item name"}}

Tha patch array operations dont work and we suppose that don't make a right JSON conversion since try to evaluate the value (LateObjectEvaluator ) with the entityValueType of the parent.

return value instanceof LateObjectEvaluator ? ((LateObjectEvaluator) value).evaluate(entityValueType) : value;

Maybe our approach is not the best solution to sync into a JPA context with OneToMany relations even if exists Lazy Fetch (where collections are PersistedBags) and could be better use shadow parent and items separated.
I hope your comments and sugestions, Great Job.
