JMWE Transition - how to access parent issue in a condition

[Brett Connor]

Using JMWE in Atlassian cloud, so Nunjucks not groovy.

I want to transition a subtask depending on a criteria of it's parent Story / Bug / whatever. The trouble is, parentIssue is null.

There's reference in the documentation that parentIssue is only set when operating on the parent issue. I read that as for example transitioning the parent issue.

Any way around this? Any way to access the parent in the condition?

In the Transition Issue post-function, only the "issue" variable is defined.

You can still access the parent issue of the current issue, using issue.fields.parent, which returns an object representing the parent issue, as documented here: https://innovalog.atlassian.net/wiki/spaces/JMWEC/pages/108200050/Standard+JIRA+fields#StandardJIRAfields-Parent

However, this object only contains a subset of the parent issue's fields, so you need to make sure the field you're interested in is available by "dumping" it first using the Template Tester:

{{ issue.fields.parent | dump(2) }}

If the field you're interested in is not there, you'll need to use the "parentIssue" filter instead, as described here: https://innovalog.atlassian.net/wiki/spaces/JMWEC/pages/138405679/Custom+Nunjucks+filters#CustomNunjucksfilters-parentIssue

Thanks David. I tried issue.fields.parent, it was null using the template tester. At least yesterday it was null. I've tried it again today and it's not, I can only guess that I was probably typing the parent issue key rather than the subtask into the template tester, or something silly like that.

Bonus, I didn't know about dump, that's dead useful.

Thanks for your help.

In which JMWE post-function are you trying to do this, and on which workflow (issue or subtask)?

[Brett Connor]

I'm using "Transition current issue", on a subtask.
