[triangle-zpug] Getting DisplayList to show Values instead of keys

[Jim Allman]

Rob, I know this is a very old thread, but I'm wondering if you found  
an answer to this question:

I've run into the same problem, and after a couple of hours digging  
through Archetypes source code, just decided to punt with a simple  
list of values, like so:

BUILDING = [
	'Bank of America',
	'Lineberger',
	'Mary Ellen Jones',
	'Macnider'
	'Medical Biomolecular Research Building',
	'Other'
]

This is less common in examples, but works just fine.

Of course, with this method the same string is used for storage and  
display of a value. Now my view templates show a friendly value, and  
so far I can't see a down-side to storing these strings as values.  
Granted, it's lousy for i18n, and it'll be a pain if the client wants  
to tweak the display names. (I suppose we'd need to revise all  
existing objects to replace old with new string values.)
Anyway, I hope this helps someone out there.
