Beta4 not Working

Have you cleared your drupal cache? Have you checked on the views settings, if everything is like it should be?

I can confirm as well, that switching to beta 4 displays a GBOD (gray block of death, where the timeline used to be). To clarify, I repeatedly changed between copies of all three module versions (beta 2,3, & 4), clearing all caches each time, with predictable, repeatable results. In fact I was waiting to see if someone else saw this issue, while I reverted back to beta 3 which runs ok.

At least when I was testing as described, I did manage to debug my installation to improve it, and I can run the timeline with local libraries installed in /all/libraries; as well as the similie server. You can private message me for the development address if you want. I can run it in debug mode for you also; otherwise I don't know what else I can report at this time.

The timeline has become a very important component to our non-governmental organization's website, and we'd like to publish it at the bottom of every page; so long as we can cache and distribute everything efficiently enough to be realistic.

Yes, this is trivial to replicate: take a brand-new drupal 6.14 installation, add the views module and the timeline module, create a node, and go to site/timeline/nodes -- GBOD.

The problem seems to be the change on line 53 of Timeline.class.inc -- which sets the 'theme' in the data array.
$this->data['theme'] = drupal_substr(strrchr($view->style_options['display']['appearance']['theme'], '/'), 1);

The problem is that style_options[...] is the string "ClassicTheme" -- it has no slashes in it, so the strrchr gets a NULL return. I changed it back to the original code
$this->data['theme'] = $view->style_options['display']['appearance']['theme'];
and everything worked okay.

Same here - timeline no longer displays.

Here is a proposed patch to fix the issue.

The patch is agains the DRUPAL-6--2-0-BETA-4 tag branch. The bug does not exist in the head; the bug was only introduced in the BETA 4 branch.

The CVS checkin for the beta 4 branch doesn't indicate why the call was changed. I'm guessing that the intent was to get the basename of the theme file, so that's what I put in the patch. The module maintainer will have to sort that out if it is incorrect.

I think i fixed this error with the lastest commit: #276704

You can test it downloading the latest version of the module's DRUPAL-6--2 branch:
cvs -z6 -d:pserver:anonymous:anonymous@cvs.drupal.org:/cvs/drupal-contrib checkout -d timeline -r DRUPAL-6--2 contributions/modules/timeline

Please mark this bug as "reviewed and tested by the community" if you can confirm that this is fixed now. So I can publish beta5.

I tested this and the bug is fixed. Still a little curious as to what the code is intending and whether the given fix is as brittle as it appears.

Let me clarify -- the bug about it not displaying at all is what I tested and is fixed. ddbell, if you are having other problems, you really need to open separate bugs for them.

Fixed with official 2.0 release.
