  |   | Fourth, if you say add an h:messages to the dropdown, what do I name the <h:message for="???? this name ????"/>.

  | <h:selectOneMenu value="#{roomFinder.example}" converter="org.jboss.seam.EntityConverter" id="example">
  |   |    <f:selectItems value="#{roomListByOrganization}" />
  |   | </h:selectOneMenu>

  |   | When I click the create button, I simply need to add a new Person record, calling the PersonEditor.create() method with the roomID, take from the room dropdown. Why do I need to go update the RoomFinder bean with that value?

I'm concerned about the fact that you are outjecting the list of rooms into the session.  Try removing the @Out, setting roomListByOrganisation as a List and but a breakpoint on the @Factory method and see when it is run and what the java variable roomListByOrganisation is set to after the  Factory method has run - check that you aren't outjecting null!
