Hibernate version:
core - 3.2.4 SP1
Annotations - 3.3.0 GA
entity manager - 3.3.1 GA

I have CollectionOfElements annotation within nested embedded classes. Class A embeds Class B. Class B then embeds Class C1 and Class C2. The CollectionOfElements annotation is in Classes C1 and C2. The collections within classes C1 and C2 are not being persisted in the database. Hibernate throws PropertyAccessException. There is also a null pointer exception

Caused by: java.lang.NullPointerException
at java.lang.reflect.Field.get(Field.java:357)
at org.hibernate.property.DirectPropertyAccessor$DirectGetter.get(DirectPropertyAccessor.java:32)
0.187

Has anybody run into the same problem? Any ideas. Appreciate your help.

Thank you,
Sriram
