Selecting a promoted build using the Dashboard web page shows the console log for that build on an URL like this:

http://jenkins/job/<project>/123/promotion/<promotion>/promotionBuild/10/

I would expect to see the artifacts for promotion build #10 on this page,
and the console output only after selecting 'Console Output' in the menu on the left. The Promotion over view page:

http://jenkins/job/<project>/promotion/process/<promotion>/

shows me the 'lastSuccessful artifacts'. It is not possible to click your way to artifacts of any other build.

Manually entering this URL:

http://jenkins/job/<project>/promotion/process/<promotion>/10/artifact/

gives me a list of artifacts for build #10. This is the page I expected for the first URL in this post.
