Scott, assigning this to you since you have been discussing this with jw in the forums. Let me know if this turns out to be some EJB interceptor issue.

> If an Entity Bean has a @PreUpdate listener, the listener is not called in the context of the caller (session bean) in case of Container Managed Transactions.
> As a result, an jndi lookup in the callback for 'java:comp/EJBContext' returns always null. The @PreUpdate callback should run in the context of the caller.

> This listener works fine on @PrePersist (Container- and Bean Managed Transactions) but fails on @PreUpdate with a NullPointerException if container managed transactions are used.
> Workaround: use User Transactions instead of Container Managed Transactions
