Use s:convertEntity and s:selectItems as demoed in a number of examples (e.g.
ui example)

The vision is that in case we don't want to use enums to populate selection
controls we could use objects instead, but those objects don't yet need to be
persisted.

You can use s:selectItems with any java object, but you need to provide a JSF
converter if the object isn't a string. JSF provides some (e.g. number
converter), Seam adds two more (enums, already persisted JPA entities), for
others, you'll need to write your own.

I see, thanks Pete and Damian.
The documentation implies that you would only ever use this with JPA entity.
Right now it looks like our system will have both JPA and non-JPA components
bound to the JSF UI. As such, we don't plan to always bind entities to
entities. Would this be possible?

Rick Hightower's series on JSF/Facelets on IBM developer works is superb IMO

Not really, the trouble is if you are using Facelets and Seam, lots of what a
JSF book is about (backing beans, jsp) are irrelevant. Your best bet is
Micheal (Yuan)'s Seam book. O'Reilly have a pocket guide to facelets that is
well worth the $10 it costs.

Here is what I came up with. I am posting it in order to elicit comments on my
approach (code review) and also in case this is right and anyone else needs to
use selectItems with a custom converter when you want to populate it using
objects. In the interest of brevity this is not a compilable
