working with jboss4.2and JPA.
i have a detached entity.
and i call to em.merge
when i add - cascade delete orphan annotation i get the following exception:
collection with cascade="all-delete-orphan" was no longer referenced by the owning entity instance
I searched in google and in the forum (
) and i saw that the reason for this exception is when you have "unstandard setters for collection", but all my collection setters are simple setters.
does any one has another idea?
It is sorta covered in the
