Do you still think a map-based rendererer is the way to go?
Yes, I would do it that way. That seems easiest to me. I do that
stuff sometimes and I declare my map to be static:
private static MapString,String CHOICES_MAP = new
HashMapString,String();
static
{
CHOICES_MAP.put(Y, Yes);
CHOICES_MAP.put(N, No);
CHOICES_MAP.put(U, Unknown);
}
Then, just use your map in your renderer (I'll leave that exercise up
to the reader). You could even use resource keys instead of
hard-coded labels. That way, the Yes stuff would be in properties
files. Enjoy!

Re: DropDownChoice with ChoiceRender problem
Try adding a selectoption in you 'backingbean'. The Dropdown choice want to
'bind' it self to the same type of property in the model as in the List that
you fill it with. If you use the generics on the dropdown it will be much
clearer.

Re: DropDownChoice with ChoiceRender problem
Why dont you let handicapaccess be of the type SelectOption.
It will contain the getId and getName. So you can get the Y or Yes if you
want to.
You could ever rename selectoption to HandicapAccessBean to make it clearer.
I have created a dropdownchoice that maps to an UUID in the Model instead of
the DropDownChoice generic type and I can say I like it.
Lets say that your working on a wizard. On the last confirm page you dont
want to show Y as the selected handicappaccess. You want to show 'Yes'. That
is easiest done by letting the model have the SelectOption as a member!
