Exception on between "Issue Commented" Event and its listener and how can I learn read it?

Question

Hi, I use ScriptRunner and fire the "Issue Commented" event on transitions. I also have a Script Listener that listens to the "Issue Commented" event that copies comments to linked issues and transitions them if needed. The Log shows the following output. I guess it is after the "Issue Commented" event is fired on the transition that is done by the script. I do not understand where the Exception happens because the log output is all Greek to me. Is there any Tutorial on how to read this exceptions? Can anybody tell me where the problem is?

Hi Peter,

Thanks for the script. Below is a script that will return to you a the last comment and the comment added during the transition

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue

def issue = event.issue as Issue
def lastComment = ComponentAccessor.getCommentManager().getComments(issue).max {it.created}
def currentComment = event.params.transientVars.comment

log.debug "Last comment : ${lastComment.body}"
log.debug "Current comment : ${currentComment}"

I think this was the part that you were missing. Let me know if this does the trick.

regards, Thanos

Hi Thanos, here is the Script Listener that handles the "Issue Commented" event: import com.atlassian.jira.issue.link.IssueLinkManager; import com.atlassian.jira.issue.link.LinkCollection; import com.atlassian.jira.component.ComponentAccessor; import com.atlassian.jira.issue.Issue; import com.atlassian.jira.issue.IssueManager; import com.atlassian.jira.issue.UpdateIssueRequest; import com.atlassian.jira.user.ApplicationUser; import com.atlassian.jira.user.util.UserManager; import org.apache.log4j.Category; import com.atlassian.jira.bc.issue.IssueService; import com.atlassian.jira.bc.issue.IssueService.TransitionValidationResult; import com.atlassian.jira.issue.IssueInputParameters; import com.atlassian.jira.issue.AttachmentManager; import com.atlassian.jira.issue.comments.Comment; import com.atlassian.jira.workflow.IssueWorkflowManager; def Category log = Category.getInstance("com.onresolve.jira.groovy.PostFunction"); log.setLevel(org.apache.log4j.Level.DEBUG); def IssueLinkManager issueLinkManager = ComponentAccessor.getIssueLinkManager(); def IssueWorkflowManager issueWorkflowManager = ComponentAccessor.getComponentOfType(IssueWorkflowManager.class); def IssueService issueService = ComponentAccessor.getIssueService(); def IssueInputParameters inputParameters = issueService.newIssueInputParameters(); def Issue thisIssue = event.issue; def thisIssueId = thisIssue.getId(); def commentMgr = ComponentAccessor.getCommentManager(); def Collection comments = commentMgr.getComments(thisIssue); def Comment newComment = comments[-1]; def Comment previousComment; if (comments.size() > 1){ previousComment = comments[-2]; } if(event){ if(event.comment){ if( event.comment.body && newComment ){ def ApplicationUser yourUser = event.user; def LinkCollection linkCollection = issueLinkManager.getLinkCollection(thisIssue, yourUser); def Collection linkedIssues = linkCollection.getAllIssues(); def ApplicationUser commentAuthor = ComponentAccessor.getUserManager().getUserByKey('helpdesk'); def String lastComment = ''; if( previousComment ){ lastComment = previousComment.getBody(); } def comment = newComment.getBody(); log.debug("newComment: " + comment + " oldComment: " + lastComment); if( comment && lastComment != comment ){ def Collection availableActions = issueWorkflowManager.getAvailableActions(thisIssue, commentAuthor); availableActions.each { availableAction -> log.debug( "Action name: " + availableAction.getName() + " ID: " + availableAction.getId()); if ( availableAction.getName() == "Provide feedback" || availableAction.getName() == "Request Feedback" || availableAction.getName() == "Ask for feedback" ){ def actionId = availableAction.getId(); def IssueService.TransitionValidationResult transitionValidationResult = issueService.validateTransition(commentAuthor, thisIssueId, actionId, inputParameters); if (transitionValidationResult.isValid()){ def IssueService.IssueResult transitionResult = issueService.transition(commentAuthor, transitionValidationResult); } } } } for ( linkedIssue in linkedIssues) { if(linkedIssue.getProjectObject().getKey() == "EXP"){ lastComment = ''; def lastCommentObject = commentMgr.getLastComment(linkedIssue); if( lastCommentObject ){ lastComment = lastCommentObject.getBody(); } comment = newComment.getBody(); if( comment && lastComment != comment ){ commentMgr.create( linkedIssue, commentAuthor, comment, true); } def AttachmentManager attachmentManager = ComponentAccessor.getAttachmentManager(); attachmentManager.getAttachments(thisIssue).each {attachment -> if(attachment.created.getTime() >= lastCommentObject.created.getTime()){ attachmentManager.copyAttachment(attachment, commentAuthor, linkedIssue.getKey()); } } } } } } } Thank you in advance!

And you mention you do something with the comments ? Can you please paste the part of your script that retrieves the comment in the transition ?
