How do we update the triggering issue in a FOR loop of linked tickets?

Howard Thompson_fd3bm9

The sequence is:

1 - When work item is updated

2 - For Linked Work Items (Blocks links)

3 - *** Need to assign the linked issue.summary to a custom field in the trigger issue

======================

This all boils down to:

TmpIssue = Triggering Issue;

TmpStr = "None";

For List of linked tickets {

  If desired ticket found then {

    TmpStr = linkedTicket.summary;

    break;

  }

}

Tmpissue.someCustomfield = TmpStr; // assigning the linked ticket summary

================================

But this kind of thing isn't supported?

https://jira.atlassian.com/browse/JIRAAUTOSERVER-985

What do you do instead? 

===============================

I have tried:

Creating variables but the scope issue from JIRAAUTOSERVER-985 means I always end up with "None"

If tried doing a JQL lookup for the original trigger issue and assigning the summary recorded in a variable but I seem to be stuck in the context of the "For list of linked tickets" rather than the result of the JQL lookup. 

=============================

Anyone have ideas?

Hello @Howard Thompson 

Welcome to the Atlassian community.

Are you anticipating finding multiple linked work items that meet your criteria or just one linked issue?

If you anticipate finding only one, what would you want to happen if you found more than one?

You could do something like this:

When work item updated
Lookup Issues: 
  JQL: issue in linkedWorkItems("{{triggerIssue.key}}", "blocks")
Advanced Compare:
  First Value: {{lookupIssues.size|0}}
  condition: equals
  Second value: 1

  Edit Work Item (this will edit the trigger work item)
    Field to set: <your custom field>
    Value: {{lookupIssues.first.summary}}

That works if you expect to find only 1 linked work item. If you find only 1, then it copies the Summary from the linked work item to your trigger work item. If it finds 0 or more than 1, then it does nothing.
