I raised
http://jira.jboss.com/jira/browse/JBSEAM-1768
for it. Besides legacy databases it is useful for us when some entities goes between
systems where the ID has no meaning and the relation has to be "denormalized" to
something that the recieving end understands.
Sure, you could probably do a converter function in the backing bean that would convert a
list of entities to a list of SelectItem:s with reflection based on a property name but
adding full EL support to it could be a little hairy. Of course, there are probably
utility classes for it in Seam but if it goes into the jsf tag it would probably be
cleaner.
