MultiWidget in MultiWidget how to compress the first one?

Question

I have two MultiWidget one inside the other, but the problem is that the MultiWidget contained don't return compress, how do i do to get the right value from the first widget? In this case from SplitTimeWidget

class SplitTimeWidget(forms.MultiWidget):
    """
    Widget written to split widget into hours and minutes.
    """
    def __init__(self, attrs=None):
        widgets = (
                    forms.Select(attrs=attrs, choices=([(hour,hour) for hour in range(0,24)])),
                    forms.Select(attrs=attrs, choices=([(minute, str(minute).zfill(2)) for minute in range(0,60)])),
                  )
        super(SplitTimeWidget, self).__init__(widgets, attrs)

    def decompress(self, value):
        if value:
            return [value.hour, value.minute]
        return [None, None]


class DateTimeSelectWidget (forms.MultiWidget):
    """
    A widget that splits date into Date and Hours, minutes, seconds with selects
    """
    date_format = DateInput.format

    def __init__(self, attrs=None, date_format=None):
        if date_format:
            self.date_format = date_format
        #if time_format:
        #    self.time_format = time_format

        hours = [(hour,str(hour)+' h') for hour in range(0,24)]
        minutes = [(minute,minute) for minute in range(0,60)]
        seconds = minutes #not used always in 0s
        widgets = (
            DateInput(attrs=attrs, format=self.date_format),
            SplitTimeWidget(attrs=attrs),
            )
        super(DateTimeSelectWidget,self).__init__(widgets, attrs)

    def decompress(self, value):
        if value:
            return [value.date(), value.time()]
        else:
            [None, None, None]

I would create just one big MultiWidget - something like DateSelectTimeSplitWidget which uses all standard widgets that you need. (3xSelect, 2xInput). After all it will be stored into one Timestamp field, right?

In fact i'm looking for 1xTextInput(date) and 2xSelect(hours,minutes), and i all ready finished, the fact is that i did not like to repeat my self, but anyway it's done. How are yoy going to do if you put the date in select?, i mean display 28, 30 and 31 number of days in the correct month? javascript? – sacabuche Apr 19 '10 at 12:15
I would use django/forms/extras/widgets.py as a starting point. if a user chooses to select an invalid date (e.g. 2010/02/30), then the form field will raise the usual ValidationError. I never bothered to implement some javascript for this case. – mawimawi Apr 22 '10 at 09:03
