With special thanks to Hugi Thordarson too of course.
Sure; I'm always mentioned in the subtext ;-).

Well, I'm not going to argue with you. :-) I will point out a
couple of
things that may affect you at some point:
- you can't use EOs as the key in a dictionary as the keys are copied
so
your implementation won't work with EOs
- ordering the keys for the UI will be problematic, especially if the
ordering is not alphabetic.

A friend has my book - however, I just downloaded the source and
looked
at PWOPopup, well great master, I have to admit that is some
impressive
work that humbles my two inverted NSDictionarys. In this particular
instance,
I, how shall I say it, disagree. I think the 2 dictionary approach is
very clean, easy and fast.

See page 209 of Practical WebObjects for PWOPopUp. Yeah, I'm
starting
to
sound like a broken record, but I did write it to give people
answers
to
questions like this at their fingertips. PWOPopUp does what you
want
and
IMHO in a good way. You can get the source from the book from

Say I have a dictionary of Integers with a string key for display.
I bind allKeys to the list. However how will I get the string when
the object gives a Integer back? Well I thought then let me
create a reverse dictionary with strings as the values and the
Integers as the key. Then in my selection methods I can one
dictionary to get the string and the other to set back the Integer.
Does any of this make sense?

Hello -
I want to do a repeating list with a popup. I thought that
NSDictionary would be good, especially now that I look to use KVC
for
everything. Anyway, my first popup with NSDictionary had me
making
two NSDictionaries with the key/values just reversed. This way I
can
get and set the popup using the two dictionaries in reverse.
Is this the way you pros do it?
