Oleg Nenashev commented on JENKINS-53860   Re: Actions from com.github.jenkins.lastchanges.LastChangesProjectAction$LastChangesActionFactory@72b8d345 for hudson.model.FreeStyleProject@40fdcb64[testing/limit-hosts] included null not assignable to interface hudson.model.Action It is somehow related to the JENKINS-53353 fix in https://github.com/jenkinsci/jenkins/pull/3608  (CC Steve Arch). It enabled proper handling of actions, and most likely it leads to proper calculation of this one. But I believe it is coincidence, Jenkins behaves correctly The Last Changes plugin returns null singleton here: https://github.com/jenkinsci/last-changes-plugin/blob/57a22d9c5814254f240365a40f5169ca834abd62/src/main/java/com/github/jenkins/lastchanges/LastChangesProjectAction.java#L61 It was introduced by Rafael Pestano 23 days ago in https://github.com/jenkinsci/last-changes-plugin/commit/57a22d9c5814254f240365a40f5169ca834abd62 . The fix changes invalid null return value to invalid singleton null. I believe that Jenkins returns error properly. According to https://javadoc.jenkins.io/jenkins/model/TransientActionFactory.html#createFor-T- , an empty list should be returned in this line     Add Comment   This message was sent by Atlassian Jira (v7.11.2#711002-sha1:fdc329d) -- You received this message because you are subscribed to the Google Groups "Jenkins Issues" group.
