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!
