How to get current issue when I use IssueLinkCreatedEvent event

[Paweł Jakimiak]

Hi,

I created a script that sets specified value in Y custom field when I set specified value in X field.
X field is "Epic Link" (type: Epic Link Relationship) and Y it "Organizational Unit" field (type: Select List (single choice).
When I set constant issue key, script works correctly, but when I place script in Script Listener and set Events to "IssueLinkCreatedEvent" my script don't see a current issue.
In console I get information about null object.

How I can get current editing issue in this case?

Actually I try get current issue by code:
Issue issue = issue.

I tried also this method:
Issue issue = (Issue)jiraHelper.getContextParams().get("issue");

but that did not help.

Hello @Paweł Jakimiak

In listeners you can get issue from event, like this

Issue issue = event.issue

[Paweł Jakimiak]

Unfortunately, I receive this error:

2018-09-04 13:50:57,414 ERROR [runner.AbstractScriptListener]: *************************************************************************************

Oh, this is IssueLink event.

Is contains IssueLink object, which have methods to retrieve source and destination issues

Issue destinationIssue = event.getIssueLink().getDestinationObject()
Issue sourceIssue = event.getIssueLink().getSourceObject()

[Paweł Jakimiak]

Thank you very much for your help. It's works.

[Aditya Wijanarko]

Issue destinationIssue = event.getIssueLink().getDestinationObject()
Issue sourceIssue = event.getIssueLink().getSourceObject()

I use this code, but it doesn't work for me. 

Can anybody help?

[Eric Lakey]

I'm getting this error too.  Has anyone solved this?

I managed to resolve it:

Issue issue = null; //Indicates a new Issue Object, without this event. doesn't seems to work

if(event.getClass().toString() == "class com.atlassian.jira.event.issue.link.IssueLinkCreatedEvent"){ // Need some way to check if link is created or deleted, i saw something like this: (event instanceOf issueLinkCreatedEvent) but this didn't work for me
     def event = event as IssueLinkCreatedEvent
     issue = event.getIssueLink().getSourceObject()
} else if(event.getClass().toString() == "class com.atlassian.jira.event.issue.link.IssueLinkDeletedEvent"){
     def event = event as IssueLinkDeletedEvent
     issue = event.getIssueLink().getSourceObject()
} else issue = issue; //In my code, I am using also "Issue updated" event, if you want only check if Link is created or deleted, just erase this

Hi @Damian Wodziński 

Did that code work for you? Your comments are saying something differently and I get a:

unable to resolve class IssueLinkCreatedEvent

Can you also post your import section?

Best
Daniel

[Daniel]

Now I know. What is often missing for beginners - which class to import. In this case do

import com.atlassian.jira.event.issue.link.IssueLinkCreatedEvent
import com.atlassian.jira.event.issue.link.IssueLinkDeletedEvent

@DanielI get the following error although I have inserted the two import statements.

 Do you have any idea what is causing this?

[Rolf Lader]

@Aditya Wijanarko I have solved the problem by paying exact attention to whether I am processing an 'IssueLinkCreatedEvent' or an 'IssueLinkDeletedEvent' event. Otherwise I'm geting the above error.

[Thierry Dalon]

The accepted answer does not answer the question.

Issue destinationIssue = event.getIssueLink().getDestinationObject()
Issue sourceIssue = event.getIssueLink().getSourceObject()

I couldn't find a way to identify which of the edited current issue is the source or the destination of the IssueLink.

The Event object does not provide the information from which issue it was triggered.

[Rolf Lader]

Hi @Thierry Dalon

From my understanding it is irrelevant from which issue the modification was done. Can you explain the reason why it is for you relevant from which issue the link modification was done?

[Thierry Dalon]

Rethinking about it yes you are right this is irrelevant: the link can be created from both sides.

hi i have this problem to, i want to delete issue link when user want to create link to another project,and user only can link issue to current project that issue is in,i try this code 

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.link.IssueLink
import com.atlassian.jira.event.issue.IssueEvent
import com.atlassian.jira.project.Project;
import com.atlassian.jira.project.ProjectManager
import com.atlassian.jira.event.issue.EventUtils

//import com.atlassian.jira.event.issue.link.IssueLinkCreatedEvent
Issue issuedes = event.issue;
Issue issuesou;

ProjectManager projectMgr = ComponentAccessor.getProjectManager();
//Issue destinationIssue = IssueLink.getDestinationObject()
//Issue sourceIssue = IssueLink.getSourceObject()
def issueLinkManager = ComponentAccessor.getIssueLinkManager()
Issue currentIssue = issuesou
//def currentProject = currentIssue.projectObject.name
def linkedIssue = issuedes
def user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()

issueLinkManager.getOutwardLinks(currentIssue.id).each { issueLink ->

linkedIssue = issueLink.getDestinationObject()

if( linkedIssue.getProjectObject().getKey() != currentIssue.getProjectObject().getKey() )
{

issueLinkManager.removeIssueLink(issueLink, user)
}

}

and i have this error 

2019-01-08 11:21:03,878 ERROR [runner.AbstractScriptListener]: *************************************************************************************
2019-01-08 11:21:03,878 ERROR [runner.AbstractScriptListener]: Script function failed on event: com.atlassian.jira.event.issue.IssueEvent, file: <inline script>
java.lang.NullPointerException: Cannot get property 'id' on null object
 at Script3086.run(Script3086.groovy:23)

i think i can not refer to sourceIssue and  event.issue; code is for destinationIssue,

please help me thank

[Damian Wodziński]

Issue issuesou; 

This indicated null object

Then:

Issue currentIssue = issuesou

So when you try to do this:

issueLinkManager.getOutwardLinks(currentIssue.id).each

It causes the problem, it cannot do anything on null object.
