How to write condition of checking linked issue's summary for Create / Clone Issue(s) Post-function

[Kris Han]

Hi everyone, 

As title, recently I faced a problem which is needing to write a condition of checking linked issue's summary on " Create / Clone Issue(s) ". This is because I want the workflow is checking whether there is already a linked issue  with same summary before creating linked issue. However, I stuck on writing this checking linked issue's summary condition. Could someone can help me on this? Thank you very much!

Hi @Kris Han ,

you can use this Groovy script in the conditional execution section of the Create / Clone Issue(s) post-function:

!issue.getLinkedIssues().any{ it.summary == "A summary" }

Hi  @David Fischer _Appfire_ ,

Thanks for your answer. However, this answer will only for checking all linked issues, but not issues in an Epic. I am actually  looking for the condition which will check "issues in Epic" linked issues' summary. For "issue.stories", this will only return linked issues' ID not summary. Do you have any idea? Thank you very much!

Hi @David Fischer _Appfire_ ,

I think I found the answer what I need, really thanks for your help. Below is the answer for my question:

issue.stories.any{ it.summary == "summary" }

Thanks for everyone!

There are a couple of steps in this.

First, you need to look for the summary in the linked issues - https://library.adaptavist.com/entity/copy-field-value-from-linked-issue is about copying values, but could easily be modified just to check.

Second, you'd need to do the blocking.  This is going to be a problem for you though.  A post-function is too late.  To have a post-function check a value and stop you going further, you actually have to force a complete crash of the process, which can corrupt your data.

Instead, you should be doing this in a validator - these gracefully halt a transition.  They return either "true - validation passed" or "false, validation failed, and here's an optional error message to give back to the user"

Hi @Nic Brough _Adaptavist_ ,

Thanks for answering my question. However, I have tried that link you posted for modifying to check linked issue summary but I fail. Could you help me to provide the script which can check linked issue's summary? Thank you very much!
