When does decompress get called

[jeffhg58]

I have the following code for the splitdatetimewidget

class MySplitDateTimeWidget(MultiWidget):
"""
A Widget that splits datetime input into two <input type="text">
boxes.
"""
def __init__(self, attrs=None):
print 'in init'
attrs1 = {'class':"vDateField required", 'size':10}
attrs2 = {'class':"vTimeField required", 'size':10}
widgets = (TextInput(attrs=attrs1), TextInput(attrs=attrs2))
super(MySplitDateTimeWidget, self).__init__(widgets, attrs)


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

But, it seems the decompress is not getting called because I get the
date time returned into 2 separate fields instead of 1.

Any help would be greatly appreciated.

Thanks,
Jeff
