Hi everybody,

I am trying to read a persisted object and clone this object by serializing and deserializing it. the object is part of a master-detail relation, so I don't serialize the primary keys because nhibernate should think that these objects are newly created.
the problem is as follows: serialization works, deserialization as well. but wenn i want to persist the cloned object, NHibernate throws an exception saying: NHibernate.HibernateException: Don't dereference a collection with cascade="all-delete-orphan":

The problem seems like the references to the detail-objects of my objects are still here. I need something like the Java BeanLib:
"Java Bean Library (beanlib) is a utilities library for use with JavaBean. Java Bean Library for Hibernate (beanlib-hibernate) is particularly handy when used with Hibernate. It allows developers to easily reuse the same pojo classes for both persistence instances and data transfer objects."

Any ideas appreciated!

br,
david
