error while deleting an issue link through groovy script

[RamakrishnanH]

We are using a post function to delete an issue link based on change of a field value. But the removeIssueLink method is throwing the following error.

the lines of code

private int removeThisIssueLink(Issue sourceIssue, Issue destinationIssue, User user, linkTypeID){
    ComponentManager componentManager = ComponentManager.getInstance();
    IssueLinkManager linkMgr = componentManager.getIssueLinkManager();
    IssueLink issueLink = linkMgr.getIssueLink(sourceIssue.getId(), destinationIssue.getId(), linkTypeID);
   if (issueLink != null) {
      linkMgr.removeIssueLink(issueLink, user);
   }
}

we put log and all the values are getting passed correctly. The error happens at linkMgr.removeIssueLink line and issueLink and user are passed correctly.

You are using a very old version of Script Runner. Nevertheless, something is null... can we see the version with your logging, and the log lines output.

Jamie Echlin, Thanks for your reply. Please find the details you asked for. We are using Script Runner version 2.1.15 and JIRA version 6.1.1.

can you put a log message immediately after the removeIssueLink line...?

[RamakrishnanH]

Jamie Echlin, we put a log message immediately after the removeIssueLink line and we noticed that line is getting printed correctly and the error message is getting printed only after that. So now it is clear the error is not due to removeIssueLink method. And we added a log message immediately after the calling line from where we can calling this method as follows. if (!found) { log.debug("Calling removeThisIssueLink for issue ------------------:::::"); removeThisIssueLink(issue, oldIssue, user, LINK_TYPE_ID); log.debug("called removeThisIssueLink for issue ------------------:::::"); } And log after the method call is not getting printed and error message comes. Any idea what could be the reason? Thanks for your help. Regards, Ramki

> we put a log message immediately after the removeIssueLink line and we noticed that line is getting printed correctly and the error message is getting printed only after that. So now it is clear the error is not due to removeIssueLink method Exactly, so you know you were looking in the wrong place. The problem is the signature of your method removeThisIssueLink... it says it returns int, but it doesn't actually return anything. So groovy tries to cast null to unboxed type "int", which can't be null. Change the signature of your method to be void, unless you actually want to return something.

[RamakrishnanH]

Thanks a lot Jamie Echlin. Can't believe such a silly mistake.
