CGI multiple select?

[John]

Hi,

In my html form, I have 'multiple select'

<select name=spred multiple>
<option..>
<option..>


This form invokes CGI routine, where I try to read selected entries from
form["spred"]

My dilemma is here:

When only one entry is selected:
form["spred"].value (will be the object selected)

When multiple entries were selected:
for o in form["spred"]:
  o.value (--> each of these will be the object selected)

Thus, I need to handle according to situation.. I though my previous
question on 'isList' can solve this matter, but somehow, all solution
suggested (isSequenceType, type, ..) cannot distinguish these two cases.
