Re: PrimaryFieldMarshaller doesn't work?

My schema is :

schema = BaseSchema +  Schema((
    StringField('description'
               , searchable=1
               , required=0
               , widget=TextAreaWidget
               )
    ,
    TextField('docfile',
              searchable=1,
              primary = 1,
              required=0,
              widget=FileWidget,
              ),
    ), marshall=PrimaryFieldMarshaller())

when I copy the content to local disk via webdav, I found a error. I
debugged and found problem lies in marshall:

    def marshall(self, instance, **kwargs):
        p = instance.getPrimaryField()
        data = p.get(instance)
        content_type = length = None
        # Gather/Guess content type
        if IBaseUnit.isImplementedBy(data):
            content_type = data.getContentType()
            length = data.get_size()
            data   = data.getRaw()

condition 'if IBaseUnit.isImplementedBy(data):' returns false so it returns
null.
