Redmine

Hi.
I have created plugin for redmine that displays issues with some additional info.
Plugin works ok.
Now i want this information to be shown on project page under issues summary.
ive read this article
http://www.redmine.org/boards/3/topics/33949

and rednder_on approach looks very promising.
ive added new plugin with hook for view_projects_show_right
code looks like this
@# lib/release_history_hook.rb

class ReleaseHistoryHook < Redmine::Hook::ViewListener
render_on :view_projects_show_right, :partial => 'bottlenecks/view_issues'
end@

bottlenecks plugin tree structure is like this

21 directories, 16 files

Ive tried to specify full path,path with extensions ...all the combinations.
When i run redmine and access project page its always gives me 404 error.
I clearly misunderstand something very basic.
I just cant find more information on that subject.
What am i doing wrong?
Also render_on seems to be deprecated. What can i use instead?
