[Zope] Generating list of objectIDs dynamically

[Ronald L Roeber]

I am trying to generate an form option list containing documents in a 
folder. 
The folder arrangement is as follows.


county -- Golden --- doc1
        |         | 
        |         -- doc2
        |
        - Silver --- doc3
                  | 
                  -- doc4

If the user has indicated they are from "Golden" county, how do I generate 
the proper list of documents in the corresponding directory dynamically 
['doc1','doc2']? If the REQUEST object includes the county=="Golden", how 
can I do something like this (which works, but is obviously not dynamic):

<form="form" method="post" action="action"
       tal:define="workingCounty request/county;
                   docs here/county/Golden/objectValues()">

How do I get the workingCounty variable to replace the "Golden" in the 
docs definition. This is probably simple, but I'm missing it. Thanks for 
any help.
