> The Delete button on the seam-gen generated edit page calls home.remove(), which effectively detaches the deleted entity. Since the edit page is redisplayed, and the detached entity is rendered in the form, clicking Save results in an exception:
> Caused by: org.hibernate.PersistentObjectException: detached entity passed to persist: org.jboss.seam.wiki.core.Foo
>         at org.hibernate.event.def.DefaultPersistEventListener.onPersist(DefaultPersistEventListener.java:79)
>         at org.hibernate.event.def.DefaultPersistEventListener.onPersist(DefaultPersistEventListener.java:38)
>         at org.hibernate.impl.SessionImpl.firePersist(SessionImpl.java:618)
>         at org.hibernate.impl.SessionImpl.persist(SessionImpl.java:592)
>         at org.hibernate.impl.SessionImpl.persist(SessionImpl.java:596)
> Overriding the persist() method and using em.merge() would solve this temporarily, I think it is better if the generated edit page would redirect to the list page after deletion.
