Enabling all faceted Search modules simultaneously crashes entire site

If you wish to use CCK Facets, make sure you have the "dev" version of Faceted Search, as stated on the CCK Facets page.

I know this problem. I had it too. I'm not sure, if there is a bug. I didn't have the time to analyze it completely. You can do the following work around:

open the module file 'faceted_search_views.module' in an editor and add the following php command:

include_once('faceted_search_ui.module');

I had similar problem, I think...

I needed CCK facets, so installed module and got an error, then I found out I needed dev version of Faceted search to use with cck facets. So I disabled the Faceted search, removed the folder from /modules folder, and replaced it with dev version. I got the same error as you. All website was inaccessible, so I got to hard edit the tables in database.

To turn off the module in database I searched in system table. In rows mentioning faceted I changed status value from 1 to 0. Site started to work, I made sure the faceted search and cck facets are turned off, then I uninstalled them properly in /admin/build/modules/uninstall and reinstalled the new dev version of Faceted search and Cck facets. It seems to work OK now.

I'm not an expert on this, but it seems to work fine. Hope it helps.

Nope! I got the same problem again, Helmut's solutions seems to fix it well. Thanks.

It is not normal to have to "manually" include faceted_search.module... The order of file inclusion in your installation seems incorrect. Perhaps there is an issue with indirect dependencies in Drupal's package system? faceted_search_views.info put faceted_search_ui as a dependency, but did not specify indirect dependencies such as faceted_search. I have now added faceted_search in the dependencies and I think that will solve the issue (with new installs at least).

This bug still exists.

I think Drupal includes each module's .module file while they are being enabled and does not do so in dependancy order. This causes the error. The dependencies do not get installed and the site is left broken.

If you enable Faceted Search Views separately this problem does not arise.

This is not normally a problem as most modules do not use classes or extend them across modules.

@jbrown: You seem right... faceted_search_views extends a base class from faceted_search_ui, but there are no guarantees that faceted_search_ui.module is loaded before faceted_search_views.module.

I've just committed a change that should fix it: A new .inc file containing the base class and that is explicitly included from any module that need that class.
