Hi zopatistas, first, as I see there are still responses for my question about testong the id, I founded the solution, you can test it, but like that: <dtml-if "id() == index_html"> anyway, I have another problem, which is that I want to change the index-html method from another method. I make a form which has a new_index_html text area, and from it, I call a Builder method which is: <dtml-var standard_html_header> <dtml-call "index_html.manage_upload(new_index_html)"> <dtml-var standard_html_footer> The problem is that zope says that there is an autorisation failure and ask me a new password. So, I think I have to change a permission somewhere, but I do not find where. How my dtml method Builder change my index_html method??? Thanks for all
