500 Error trying to access /knowledgebase

[markus61]

i like the idea of having something that collects know-how across projects. this module seems to exactly address that. so i gave it a try while setting up our new redmine environment (latest 2.2 from svn).
knowledgebase is the only active module right now. after succesfuly adding some content i suddenly got stuck with a 500. tried an 'ordinary user' and root, no difference.
found this in the log:

...
  Rendered plugins/redmine_knowledgebase/app/views/articles/_list.html.erb (9.3ms)
  Rendered plugins/redmine_knowledgebase/app/views/knowledgebase/index.html.erb within layouts/base (28.6ms)

    4:     <%= link_to truncate(article.title, :length => truncate_length), { :controller => 'articles', :action => 'show', :id => article.id }, :title => article.title %>

    6:   
    7: <% end %>

i don't speak ruby, i hardly know what rails are - wouldn't mind if u call me dummy.
thanx for your work!

cheers,

Hi, I fear that the problem is related to the fact that you're using redmine 2.2.X: the latest version of redmine supported by the plugin is 2.0(.3). For the moment I don't have any spare time for upgrading the plugin: I even don't ask you to downgrade redmine to 2.0, because I think that it's the wrong approach (things should go always ahead and so on).

As soon as I have some news regarding the plugin update, I'll update the issues page.

as much as i would appreciate an upgrade of the timesheet plugin to redmine 2.2, as much i have to apologise for filing an issue for the knowledgebase-plugin in the issue-que of your timesheet plugin.
usually i am very thoroughful, bright and clever ;-) cheers, /markus
