hi zope experts...
i sent a message to the mailing list a few days ago about netscape and a <!--#tree--> that refuse to work with each other. unfortunately, i haven't gotten any reply yet :( i need to get this solved before the project demonstration (i *know* my professor has netscape on his machine)...
here's the situation: i have a "help" menu which is based on the tree tutorial included in the ZBook. i basically reused the same code and just renamed object references where needed. i have just one folder in the tree (called "How to...") and the folder contains DTML docs with IDs like "Use this help system" or "Search for a customer record" etc.
everything displays and works fine with IE 4, IE 5, the StarOffice browser (SO 5.1), but *not* with netscape. i tested it on NS 4.51 on Linux as well as the Win32 version of Mozilla Milestone 8. expanding the book content in the navigation bar works fine so that i see all topics. but once i click on one of the topics ZServer restarts and netscape gives me something like "document contains no data".
ouch.
am i doing something wrong? or is it some bug in netscape? please help...
Here is the code to link to the help topic pages (again, it's the very same used in that tutorial):
<IMG SRC="<!--#var SCRIPT_NAME-->/HelpSys/hs_dnode" ALIGN="TOP" BORDER="0" width=16 height=16> <A HREF="<!--#var "help.absolute_url()"-->/<!--#var tree-item-url-->?<!--#if tree-s-->tree-s=<!--#var tree-s--><!--#/if--><!--#if tree-e-->&tree-e=<!--#var tree-e--><!--#/if--><!--#if tree-c-->&tree-c=<!--#var tree-c--><!--#/if-->"><!--#var title_or_id--></a><!--#/if-->
Can you send the whole tree tag snippet?
Here is the error trace that dumps onto my linux terminal window when ZServer goes down, it's always the very same message:
uncaptured python exception, closing channel <zhttp_channel connected 192.168.168.3:4137 at 844fe00 channel#: 1 requests:0> (exceptions.TypeError:unpack non-sequence [/usr/src/Zope-2.0.0a3-src/ZServer/medusa/asyncore.py|poll|59] [/usr/src/Zope-2.0.0a3-src/ZServer/medusa/asyncore.py|handle_read_event|285] [/usr/src/Zope-2.0.0a3-src/ZServer/medusa/asynchat.py|handle_read|126] [/usr/src/Zope-2.0.0a3-src/ZServer/medusa/http_server.py|found_terminator|44 4])
Looks like it happens way down in ZServer. yikes. I would not put it past netscape to be doing some bonehead HTTP violation. -Michel
hi michel, thanks a bundle for answering. here is the complete "help_menu" DTML method which implements the tree: <SPAN CLASS="tree"> <!--#tree help branches_expr="objectValues(['Folder', 'DTML Document'])" nowrap=1 sort=id--> <!--#if expr="meta_type == 'Folder'"--> <!--#if tree-item-expanded--><IMG SRC="<!--#var SCRIPT_NAME-->/HelpSys/hs_obook" ALIGN="TOP" BORDER="0" width=16 height=16> <!--#else--><IMG SRC="<!--#var SCRIPT_NAME-->/HelpSys/hs_cbook" ALIGN="TOP" BORDER="0" width=16 height=16><!--#/if--> <!--#var title_or_id--> <!--#else--> <IMG SRC="<!--#var SCRIPT_NAME-->/HelpSys/hs_dnode" ALIGN="TOP" BORDER="0" width=16 height=16> <A HREF="<!--#var "help.absolute_url()"-->/<!--#var tree-item-url-->?<!--#if tree-s-->tree-s=<!--#var tree-s--><!--#/if--> <!--#if tree-e-->&tree-e=<!--#var tree-e--><!--#/if--><!--#if tree-c-->&tree-c=<!--#var tree-c--><!--#/if-->"> <!--#var title_or_id--></a><!--#/if--> <!--#/tree--> </SPAN> if it is indeed some netscape error i am surprised no one else has mentioned it. most people on the list seem to be using it.
