Create Issue error : null

When I trying to create a subtask issue automatically on creating issue.

I am getting this error.

The Issue is created but subtask issue is not created.

The code is as follow:

protected void createSubTask(Map<String, Object> transientVariables, Map<String, String> args)


Issue originalIssue = (Issue)transientVariables.get("issue");

Issue parentIssue = originalIssue;

MutableIssue issueObject =this.issueFactory.getIssue();



Map params =new HashMap();

params.put("issue", issueObject);



User user = ComponentManager.getInstance().getJiraAuthenticationContext().getLoggedInUser();

Issue subTask =this.issueManager.createIssueObject(user, params);

this.subTaskManager.createSubTaskIssueLink(parentIssue, subTask, user);




catch(Exception e)


log.error("Unexpected exception", e);

Thanks for your time Nic and AUser

I am cleared with the error.

The error was due to following statement


It is returning null and abnormally terminating the execution.

You don't say what error you are getting.


Yes, that's about as useful an answer as me building a tree for my imaginary penguin.

Where does the error occur and what debugging have you done and what were the results?

I havent done anything, bcause I am not the the user who posted that question!

There is a missing "?" behind my comment, because i wantet to know if this is the exception or one of his data is null.

That'y your point of view! I also could have asked him in which line the error occures. And this doesn't gets us anywhere, too.

Bharadwaj - excellent, thank you for

AUser - it's great to want to contribute, but being completely unclear really doesn't help. Even with a ? on the end, you're simply prompting the response of "yes", which gets us nowhere.
