widget construction issue

Hi,

I built a widget class that inherits form MultiWidget and it looks like this :

class GridWidget(forms.MultiWidget):

    def __init__(self, attrs=None, queryset=None):

        self.queryset = queryset 

        _widgets = []

        for record in self.queryset:

            .

            do stuff

            .

        super(GridWidget, self).__init__(_widgets, attrs)

This basically adds widgets to the _widgets var based on the queryset. 

Then I have some form that has a field like :

class PersonAdminForm(forms.ModelForm):

          attrs = MultiTypeField( \

                    label='Attributes',

                    queryset=Attribute.objects.all()

                    widget=GridWidget(queryset=Attribute.objects.all()),

                    )

The thing is that the GridWidget.__init__ method does not get executed

each time I access the form that contains it, so if the queryset changes the

widget gets 'obsolete'.

Is this some cache issue ? is there any way to force the widget construction each time i

access the form containing it ?
