I can't confirm if by "on the left" you mean the scrollable panel that
links to anchors on the page.

Please CC the mailing list on followups.

The problem only with javascript. Once it's disabled all works.

I confirm that nothing happens when clicking on the links in the left sidebar
of the above mentioned page -- though my Firefox is not blocking JavaScript.

I see the same thing as Renger: there may be links on the left, but the
page itself seems empty except for title, date, author, org version and
the HTML validation link - in particular, no anchors.

If I look at Page Source I can see everything, so somehow the
outline-containers have become invisible for me.

I ran firebug and got this error

,----
| b.CI is null
| [Break On This Error] b.HI=(b.HI+1)%50;}b.SKIP_H=false;b.CI....[a.HI]){var b=parseInt(a.H[a.HI][0]); 
`----

on line 172 of org-info.js, but I don't know if this is real or a red
herring.

Also when the pointer hovers over e.g. "Older changes" i.e. the last
link in the scrollable list, the echo area (lower left where the link is
shown) shows:

javascript:org_html_manager.go(278)

but clicking does nothing (except pop up another instance of the above
error in the firebug console).

HTH,
Nick

Re: Org-Mode Homepage error

Hi all and Sebastian,

thanks for signaling this problem -- I fixed it on the server.

This commit creates problems when exporting using org-info.js: 

  http://orgmode.org/w/?p=org-mode.git;a=commit;h=2f1fbc58be1dc48621217d666da7bc46c3c5d84e

This is no real surprise, as the commit changes the underlying
div structure of an HTML page produced by Org...

Sebastian, what would be need to make org-info.js compatible
with both the old HTML structure and the new one, which is:

<body>
  <div id="preamble"> 
  </div>

  <div id="content">
  </div>

  <div id="postamble">
  </div>
</body>

(With the "preamble"/"content"/"postamble" strings being defined
in the variable `org-export-html-divs'.)

If that's too complicate, perhaps we can enforce another structure
for divs.

Thanks for your time!

I fear this is above my current capability. I tried to understand that code
for a while, but never succeeded (in a reasonable time) to, and never could
simplify it as I wanted (to use it for my own). Of course, this is mainly due
because of my inexperience in good tools to test and debug JS, and to my lack
of knowledge of that language.

But, what did you do to fix the problem?  The current structure of the HTML
page looks good, and follows the above skeleton (except there is no preamble).
So, everything looks right to me?

Best regards,
  Seb

Well, I re-published Worg using an older version of org.

No.  The current HTML structure breaks compatibility with Sebastian's
tool.  As this is a severe bug, any help on finding a way to fix this
is more than welcome...

<mode lazybum>
Can you sum up how the div structure changes?

What was the structure before and what is it now?

I fail to understand why an additional <div id="preamble"> 
should break Sebastian's tool.

For starters, the title now resides in the preamble, but the script
looks for it in content.  This error is easily fixed, but I don't know
if it has further repercussions.

Good catch!

FYI, the title has always been in the preamble. See lines 354--381 in
org-html.el:

#+begin_src emacs-lisp
(defcustom org-export-html-preamble t
  "Non-nil means insert a preamble in HTML export.

When `t', insert a string as defined by one of the formatting
strings in `org-export-html-preamble-format'.  When set to a
string, this string overrides `org-export-html-preamble-format'.
When set to a function, apply this function and insert the
returned string.  The function takes the property list of export
options as its only argument.

Setting :html-preamble in publishing projects will take
precedence over this variable."
  :group 'org-export-html
  :type '(choice (const :tag "No preamble" nil)
		 (const :tag "Default preamble" t)
		 (string :tag "Custom formatting string")
		 (function :tag "Function (must return a string)")))

(defcustom org-export-html-preamble-format
  '(("en" "<h1 class=\"title\">%t</h1>"))
  "The format for the HTML preamble.

%t stands for the title.

If you need to use a \"%\" character, you need to escape it
like that: \"%%\"."
  :group 'org-export-html
  :type 'string)
#+end_src

The difference I introduced is that -- when present -- the preamble (whatever
its contents) is wrapped inside a "preamble" DIV.

I did not change the fact that the title was part of the preamble.

Though, we can wonder if it makes sense to put the title as part of the
preamble. But I guess there is a good reason for it(TM).

Best regards,
  Seb

Mhh...  I tried to patch org-info-src.js with this fix, to recompile 
it (and get org-info.js).  I copied the result here:

  http://orgmode.org/org-info2.js 

Then setting this path in `org-infojs-options', I tried various ways 
of getting a working HTML file, with the new div structure, but with 
no good result.

I have taken the simplest road for now: I've put the title back in the
"content" div and removed it from the default preamble -- although you
can still add it in the preamble.

I think it's better since it doesn't break people's configuration when
using org-info.js.

For such changes about the HTML structure, I need to better sync with
Sebastian to see how org-info.js can be updated and/or more flexible.
For example "content" is hardcoded in org-info.js and is not anymore 
in org-html.el, so this might lead to troubles.

Thanks for your input so far,

I didn't have time to check if the change survives the minify script and
was out the last two days.  The unminified version did work on the Worg
writeup from Sebastian Rose.  Since he appears not to have responded to
this thread so far I'll try to check what the issue with the minified
version might be.

That is the same file I have produced myself now.

Could you be more specific what is a "no good result"?  I've been
generating the index.html in org-info-js and it now works without error
for me.  I've even found a simpler patch that is based on the class
of the title heading so that it is found regardless of its position in
preamble or content:

It seems that there may be an implicit assumption that the title is in
the same DIV as the content.  This seems to work OK in FF5 and
Konqueror 4.6.5 (WebKit), however it may break in other browsers.

If you're confident this works with this structure:

  <div id="preamble">
    <h1 class="title">Title</h1>
  <div>
  
  <div id="content">
  ...
  <div>

then I will apply the patch (with a ChangeLog!)

Thanks,

Fetching a stale copy from cache perhaps?  I did all my testing locally
and changed things around to make sure it would really load the version
I just created...

That works for me in Firefox6 and Konqueror (both KHTML and WebKit mode)
in both the minified and the source version.  I've used the latest
version of yuicompressor (2.4.6 instead of 2.4.2), but that should not
make a difference.  Proper patch attached.

Thanks for this -- it does not apply, though.  Make sure you
pulled the lastest version of Worg, see commit cd473c26:

  cd473c26 * Test update of org-infojs

This was a test I did.  Since the version of org-info-js in Worg is
*not* the version on http://orgmode.org/ changes here do not affect
org-info-js users.

Let me know,
