Re: Removing entities in OneToMany with RequestFactory & JPA

do you have nulls in your expert collection in your product object?

If you have detach in your CascadeType, it works anyway if you do this

product.getExperts().remove(expert);
em.merge(product);
em.remove(expert);

The remove cascade type removes the need for a distinct remove call.
