How to counts the number of times a specific value is selected? (using JMWE)

[RIZKY JTUASIKAL]

The example is like the picture above, 

I have 5 subtasks, and I have a Rollback field with the value Yes or No.

The question is,

How do I calculate that there are 5 subtasks that have a value of YES for Rollback field?
When moving from status A to status B

Need help..

Thank you :)

Hi @RIZKY JTUASIKAL 

During that transition from status A to B, are you trying to do that calculation in a post function or in a condition or validator? The solution is different because the scripting language is different (Nunjucks vs Jira Expressions)

Hi @David Fischer ,

thanks for replying.



I will probably use the post function.

Can this be use by using Set Issue Field?

Hi @RIZKY JTUASIKAL 

yes, you can use a Set Issue Fields post function, and the Nunjucjs value you want should be something like:

{{issue | subtasks("customfield_12345") | filter(["fields.customfield_12345.value","Yes"]) | length }}

where you'll replace customfield_12345 with the custom field ID of the Rollback field (which you can find on the Issue Fields help tab)
