[Zope] Formulator acts funny for 2-character options

[Jean Jordaan]

Hi Martijn & all

This code,

   context.REQUEST.SESSION.set('state_evaluate_items', ['yes', 'no'])

in a state helper for this field::

     evaluate = fields.RadioField('evaluate',
         title='Please contact me for a full evaluation')
     evaluate.tales['default'] = "form/REQUEST/SESSION/state_evaluate"
     evaluate.tales['items'] = "form/REQUEST/SESSION/state_evaluate_items"

causes this HTML to be rendered::

   <input value="yes" name="field_evaluate" type="radio"  />yes<br
   /><input value="o" name="field_evaluate" type="radio"  />n

This is also the case for MultiCheckBoxFields and other fields
with items.

I'm assuming it has to do with this behaviour::

         A list item can also be a tuple consisting "
         "of two elements. The first element of the tuple should be a string "
         "that is name of the item that should be displayed. The second "
         "element of the tuple should be the value that will be submitted.

and that a 2-char string is misrecognized as a 2-item tuple, but
I can't figure out where in the code it occurs. Where should I
start looking?

I'm using Formulator-1.4.1, but I did a diff with CVS HEAD and didn't
notice anything that looked like it addresses this issue.
