I have noticed that this happens only when you extend GenericManagerImpl
(in the impl) and GenericManager in you interface. If you do not extend
these classes and interfaces it works alright. Hope this helps people
to get closer to the bug?
My implementation which works.

Hello Appfuse crew,
Initially upon following the tutorial in which a Person object was created
and edited, I could edit the various person objects in the database.
However now that I have re-checked the project out I recieve the following
error when editing/creating and saving (only) Person objects:
Data Access Failure
Write operations are not allowed in read-only mode (FlushMode.NEVER) - turn
your Session into FlushMode.AUTO or remove 'readOnly' marker from
transaction definition
What could be causing this? (I'm new to Hibernate, it looks like maybe a
Hibernate error, or possibily something to do with the MySQL database.) Oh
and By the way I can edit user profiles without any trouble.
Thank you,
(for making Appfuse, and helping with my questions)
