Personally I like it the way it works now. I have my custom "auto- 
generation" method in the view class (render_form()) that is called by  
my page template

        <div id="edit_form" tal:content="structure view/render_form">
             The form...

It basically revolves around:

	for widget in self.widgets:
             outp += '<tr class="row">\r'
             outp += '<td class="label"><label for="' + widget.name +  
'" title="' + widget.hint + '">'
             outp += widget.label + '</label></td>\r'
             outp += '<td class="field">' + widget() + '</td>\r'
             if widget.error() is not None:
                 outp += '<td class="error">' + widget.error() + '</td> 
             else: outp += '<td></td>\r'
             outp += '</tr>\r'

It works well, giving me control over the layout without any hassle.
