Subject: [Zope] Handling results from <select> tag
Consider a form:
<form action="Post">
    <select name="Values" multiple>
      <option value="A">A</option>
      <option value="B">B</option>
      <option value="C">C</option>
   </select>
   ...
I have the request handling stuff working 100%, except for 
the case when
the user selects only a single value. This seems to be because Zope
converts result values to a list. So, if the user selects multiple
values, form.Values becomes a list, like:
['A', 'B', 'C']
But if the user selects a single value, form.Values becomes a single
value, like
'A'
How do I effectively and foolproofly handle this sort of case?
<form action="Post">
    <select name="Values:list" multiple>
      <option value="A">A</option>
      <option value="B">B</option>
      <option value="C">C</option>
   </select>
will allways make 'Values' a list.
