Thanks Pete,  

so instead of just letting EJB inject my entity manager automatically


  | private EntityManager em

I should let Seam do it instead?


  | @In
  | private EntityManager em

By specifying @In it will always know to get the Seam EntityManager from the 
EntityManagerFactory?

As far as the Dialog stuff, what I like about Trinidad is the built in 
tr:inputListOfValues control which displays a popup to get values from.  It is 
useful when a Select/DropDown box just won't do.  It also does PPR to issue a 
refresh when the value returns to the calling page.

In Seam I can use an s:link to propagate the conversation to the popup and I 
guess some JavaScript to make it a new window (Trinidad has an attribute 
useWindow that does this).  How would I go about getting the value back to the 
calling page? Bijection?  How does the calling page know to refresh/ppr?

Thanks again!
