java.lang.NullPointerException: Cannot invoke method setIssue() on null object

Question

Hi,

I had a working script but after upgrade to JIRA 8.5. I have to replace component manager.

I did that but now i get Null pointer exception.

Below is the script. Any help is appreciated.

import com.opensymphony.workflow.WorkflowContext;

boolean check = false;

String currentUser = ((WorkflowContext) transientVars.get("context")).getCaller();

issueLinkManager.getOutwardLinks(issue.getId()).each

{
workflowTransitionUtil.setIssue(linkIssue);    <== ISSUE HERE
workflowTransitionUtil.setUserkey(currentUser);
workflowTransitionUtil.setAction(51);

Hi @Madhavan Jayabalan ,

Did you get any resolution to your issue?

I am also facing the same error

workflowTransitionUtil.setIssue(parent) <== Issue is here

I have even replaced

WorkflowTransitionUtil workflowTransitionUtil = (WorkflowTransitionUtil) JiraUtils.loadComponent(WorkflowTransitionUtilImpl.class){Depracated}with WorkflowTransitionUtil workflowTransitionUtil = (WorkflowTransitionUtil) ComponentAccessor.getComponent(WorkflowTransitionUtilImpl.class)Problem: setIssue() is throwing java.lang.NullPointerException errorLet me know if you have any workaround you did.ThanksLipsa

Hello @Madhavan Jayabalan, I am running Jira v8.5.3. I do not get the error you get, and my script is run as a "Script Listener".

I'm doing it slightly differently, have you tried replacing:

WorkflowTransitionUtil workflowTransitionUtil = (WorkflowTransitionUtil) ComponentAccessor.getComponent(WorkflowTransitionUtilImpl.class);

with

WorkflowTransitionUtil workflowTransitionUtil = (WorkflowTransitionUtil) JiraUtils.loadComponent(WorkflowTransitionUtilImpl.class)

I wouldn't think that will matter, but I'm also setting

workflowTransitionUtil.setIssue(issue);

but here, my 'issue' is of type 'Issue', not of type 'MutableIssue'.

Hi Daniel,

Thanks for the support.

I referred the documentation you have referred but still i am unable to make my script working. Looks i'm missing some basics.

In the script which i have in the description(above). I see that linkIssue is null. Eventhough i'm able to get summary and issue type etc from linkIssue.

workflowTransitionUtil.setIssue(linkIssue);    <== ISSUE HERE

Cheers,

Madhavan.J
