I have a sample Maven job configured. From /job/mercurial-plugin/ there is a link /job/mercurial-plugin/deleteAllDisabledModules which works (whatever it does). But if I first click on the "Workspace" link, and then click on "Delete All Disabled Modules", I am taken to /job/mercurial-plugin/ws/deleteAllDisabledModules which is a 404. (Similarly for other actions which have a basedir, e.g. /job/mercurial-plugin/move/deleteAllDisabledModules when using the Folders plugin.) Seems like MavenModuleSet/actions.jelly is failing to set a proper base URL.
