I have Cc to twisted-web, hoping this will help the archiving. > Just for future reference, here is an alternate solution. It contains more code, but it is more database friendly (and I like this - better performance too?). It also contains some correction for the HTML code. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";> <html xmlns="http://www.w3.org/1999/xhtml"; xmlns:n="http://nevow.com/ns/nevow/0.1"; lang="it" xml:lang="it"> <head> <title>Nested sequence II</title> </head> <body> <form action="post" method="post"> <ul n:render="sequence" n:data="control_list"> <li n:pattern="item" n:render="control"> <label><n:slot name="ctrl_label"/> <select n:render="option_list"> <n:attr name="name"><n:slot name="ctrl_name" /></n:attr> <option n:pattern="item" n:render="option"> <n:attr name="value"><n:slot name="opt_value" /></n:attr> <n:slot name="opt_label" /> </option> </select> </label> </li> </ul> <input type="submit" value="send" /> </form> </body> </html> class Main(rend.Page): addSlash = True docFactory = loaders.xmlfile('nestedsequence.xhtml') def data_control_list(self, ctx, data): return [('a', 'first'), ('b', 'second')] def render_option_list(self, ctx, data): option_list = [('1', 'uno'), ('2', 'due')] tag = ctx.tag pattern = inevow.IQ(ctx).patternGenerator("item") content = [pattern(data=option) for option in option_list] return ctx.tag.clear()[content] def render_control(self, ctx, data): print '*', data ctx.fillSlots('ctrl_label', data[1]) ctx.fillSlots('ctrl_name', data[0]) return ctx.tag def render_option(self, ctx, data): ctx.fillSlots('opt_label', data[1]) ctx.fillSlots('opt_value', data[0]) return ctx Maybe it is not reusable as the previous solution, but it's not a problem.
