[Zope3-dev] Re: Widget problems? Is there work in progress?

[Roger Ineichen]

The method _toFieldValue confuse me a little bit.

My open questions are:

- The attr convert_missing_value means we 
get the self._missing back if we set to True
otherwise we get the unicode(value) back?

Should the if statement not looks like this:

if self.convert_missing_value and self._missing:

----
def _toFieldValue(self, input):
    if self.convert_missing_value and input == self._missing:
        value = self.context.missing_value
    else:
        # XXX We convert everything to unicode :-(
        # But I see no other way for to convert the
        # value at the moment. 
        try:
            value = unicode(input)
        except ValueError, v:
            raise ConversionError("Invalid integer data", v)
    
    return decode_html(value) 
---

- Should we also convert the _missing? Or not, for 
to provide None as possible missing value otherwise 
we whould get a u'None'?

- What should we decode in the method decode_html?
Is this for unexcepted use of the TextWidget?
Or why should a <input type="text" value=""> tag 
contain HTML Code? The TextAreaWidget does.
This means also we can't store unconverted 
HTML tags with this widget or at least '<' and '>'.
