The filter parameter doesn't change the contents of the list. See screenshot.
You don't have jquery in jenkins please install jquery plugin
Thanks Boguslaw, installing the JQuery plugin (https://wiki.jenkins-ci.org/display/JENKINS/jQuery+Plugin) resolved this issue for us.
As this is a dependency, does it make sense to declare it? As per https://wiki.jenkins-ci.org/display/JENKINS/Dependencies+among+plugins
Confirmed as a fix Would be nice to make it a dependency.
Adam Kapos, George Sakhnovsky thanks for using this plugin and testing it. I would add dependency in next release
