[jboss-user] [JBoss Seam] - @Rollback annotation for validation logic causing detached o

[p2auljr]

I have a stateful session bean that uses an extended persistent context and is annotated with @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED). 

In a transactional action method annotated with @TransactionAttribute(TransactionAttributeType.REQUIRED), I perform business level validation. If the validation fails, I rollback the transaction using Seam's @Rollback annotation. 

However, the EJB specs indicates that a rollback will cause all entities in the entitymanager to be become detached. This seems like overkill because then I need to merge back all the instances and allow the user to fix the validation errors. 

Are there any best practices with this? Should I only rely on using Hibernate validation with seam's s:validateAll tag? 

Thank you.
