I have emailed you before and asked you not to use the PATH_INFO variable, but instead to use BASEx, URLx and absolute_url(). This was fixed for some action tags. But NOT the breadcrumb at the top. Please fix :) Can you please not use the Zope submit button magic. It causes problem. Please use straight forward HTML forms:: <form action="contacts/manage_add_address_book_contact_form" method=post> <input type=submit value="New contact"> </form> And to loose the unnecessary extra space this causes, hide it in tables. <table><tr> <form action="contacts/manage_add_address_book_contact_form" method=post> <td><input type=submit value="New contact"></td> </form> </tr></table> Does it matter that I created a Addressbook with the id: "contacts"? Considering that this id is used for other things as well. I get a lot of 404's message by clicking the buttons. More bugs/feature requests to come as I have time to use it more. Best regards, Peter
