I think it's impossible to tell the difference. The way form fields are
encoded, a single item selected in a multiple select list is the same as an
item selected in a single select list.
What I did is to write a method in my SitePage.py:
def listField(self, name):
values = self.request().field(name, [])
if not isinstance(values, types.ListType):
values = [values]
return values
Then instead of using reg.fields()["myselect"], I use
self.listField("myselect"). It'll always come back as a list.
