Hi,
You have to initialize the collections before AMF serializes them. The
problem occurs since you closing Hibernate session without first
initializing the arrays, and since you are using lazy initialization the
problem arise.
You have two options :
1. Use lazy=false
2. Better one, is calling /Hibernate.initialize(your_array_reference);/
before you close the Hibernate session.

Dima Gutzeit.
