You only do this once, when extracting the data out of the object instance (or the defaults). The data is already 'flat' when it comes out of a POST. do_html2python gets it back into a form suitable for both saving and populating form fields.
What you are doing here is getting the default data out of the manipulator again as far as I can tell.
