Right, that is the problem.  I load the customer into the session-scope, and that works.  Now I want to display some collections that are referenced by the customer object on some other pages.  That won't work because there's no conversation and thus no conversation-scoped SMPC.

Ok, then how do I handle this?  I've got a Customer in the session, and now I need to start a conversation with the same customer entity in it.

I could have a conversation-scoped bean with some other field, like conversationCustomer.  I could then do:

conversationCustomer = entityManager.merge(customer);

but that seems wrong because I'm not really doing a merge.

What do you think of this?  Surely this is a fairly common situation, where there is a user object that's in a session, and then we need to have that user attached to a PC so we can display collections from that user?  There must be some standard approach to this?
