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

[Madhavan Jayabalan]

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.

workflowTransitionUtil.setUserkey(currentUser);

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 Madhavan,

there have been some changes when upgrading to Jira v8. You mentioned the replacement of the ComponentManager - this is indeed a significant one. From my experience simple replacing it won't work.
The Groovy scripts needs a rework in some cases.

Have you checked the documentation on this?
https://scriptrunner.adaptavist.com/5.6.8/jira/releases/UpgradingToJira8.html#_componentmanager_has_been_moved

In case you don't get along with the generic documentation please state where the NPE exactly occurs. The likeliness is then higher that somebody from Community will look into the code and give an advise.

Cheers,
Daniel

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,

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 error

Let me know if you have any workaround you did.

Thanks

Lipsa
