Correct. I'm probably presumming too much. Something is happening that I'm not seeing. I do not see any exceptions.
anonymous wrote : 2) What does <h:messages /> give for the dropdown box. You've probably hit a conversion error. (You have <h:messages globalOnly="true" /> but none for the h:selectOneMenu)
I think my problem is complex. First of all the code that I am working with was generated using the hibernate code generation tool(This is a good thing). Second, I am taking the generated PersonEditorBean/jsp and trimming it to just a few fields(a quick add). Third, the roomId, needs to be a lookup/dropdown against the room table. So, how the heck do you do this using seam? Fourth, if you say add an h:messages to the dropdown, what do I name the <h:message for="???? this name ????"/>.

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?

If I remove the @Out, I get this:
