I've a Zope newbie, trying to set up a Zope site at zope.org, and I'm running into problems with what seems like it should be a fairly simple navigation method. I've replaced the standard_html_header and footer methods with my own, which create a simple two column table; I'm trying to get the navigation information into the left column. I've established a nav_title property on the two pages that I want to show up in the navigation list, with the values "Home" and "Biography", and I've written a nav_vertical method to display the list: <dtml-in objectValues> <dtml-if nav_title> <a href="&dtml-absolute_url;"><dtml-var nav_title></a><br> </dtml-if> </dtml-in> I've embedded a call to that method in the standard_html_header method: <html> <head> <title><dtml-var title_or_id></title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <body bgcolor="#FFFFFF"> <table width="90%" border="0" cellpadding="8"> <tr> <td align="center"><img src="http://www.zope.org/Members/rblumberg/images/rbRight" width="50" height="60"></td> <td valign="bottom"> <h2><dtml-var title></h2> </td> </tr> <tr> <td valign="top"><hr> <dtml-var nav_vertical> <hr></td> <td> (The table cells are closed in the standard_html_footer.) Now, the nav_vertical method works exactly as planned when I call it directly: http://www.zope.org/Members/rblumberg/nav_vertical The header method also displays correctly (even without the closing tags, at least in MSIE 5) when it is called directly: http://www.zope.org/Members/rblumberg/standard_html_header But the pages which call the new header don't display the navigation list: http://www.zope.org/Members/rblumberg/index_html Is this a bug in Zope, or am I doing something wrong?
