[jboss-user] [EJB 3.0] - What is the best way to re-attach a detached entity?

I have an object called customer. I'm using Seam, and an EntityManager is injected, and a customer object is successful injected. I try to merge the customer back like this: entityManager.merge(customer); but that does not work, because after that, I do: if(! entityManager.contains(customer)) log.severe("Oh no it did not work"); Of course, it logs that the entityManager does not contain the customer. What is the best way to re-attach a detached entity? Should I do: customer = entityManager.find(Customer.class, customer.getId()); ? That seems like it would re-attach, but surely there is some method within EntityManager to re-attach a detached entity without doing a find on it?
