Ok, that clarifies things.  I was using EntityHome, which is conversation scoped (in Home.java superclass).  Then I was using other POJOs and wondering, why are these things not starting conversations?  Now I see.  I need to put @Scope(CONVERSATION) on them.

For many simple things there is no performance benefit to clustering beans. So, should we be using EJBs or POJOs? POJOs have a benefit of simplicity: no need to write an interface.

Ok, now I'm getting it.  I'll use POJOs.  Are there any other limitations on POJOs that are significant for routine use?  For example, I assume I can do all the same Seam security stuff on POJOs that I can on SFSBs?  And I assume that POJOs can be members of long-running conversations, and can use @Begin and @End on them?  This last factor (being in long-running conversations) is the most important.
