[Product-Developers] z3c.form - unicode problem

[Umberto Calligaro]

I've solved the problem setting "ignoreContext = True", then I populate the
form in "updateWidgets" method with this code:

for key in self.widgets.keys():
    value = getattr(self.context, key)
    if isinstance(value, str):
        value = unicode(value, "utf-8", errors="ignore")
    if IDatetimeWidget.providedBy(self.widgets[key]):
        value = DateTimeParser().parse(value.strftime('%Y/%m/%d %H:%M'))
    self.widgets[key].value = value


Thanks again
Umberto Calligaro
