I have a nested view with two portlets: A job list and a unit test statistics grid.
On one of the two, I get absolute links based on what's configured in "Manage Jenkins... Configure System... Jenkins URL" instead of just relative links starting with "/"
Here's an example: My build server's DNS name is "build.foo.com", but I'm also configuring a new build server "newbuild.foo.com". I've configured on both that the Jenkins URL is "http://build.foo.com".
Working on "newbuild.foo.com" shows the problem:
Jenkins normally doesn't care about that configuration when creating links to jobs: For my "base" job for instance, I get <a class="model-link inside" href="job/base/">base</a>
But in the Nested View Plugin, I sometimes get the URL above, but also <a class="model-link" href="http://build.foo.com/view/bar/view/Projects/job/base/">base</a> - which means that the configuration is used to build that link.
