When you add this post-function to a transition and trigger it, each post-function defined in the sequence is run, one after the other on the target issues. 

Issue(s) to operate on

Select the issues on which the sequence of post-functions should be run. They can be:

• Current issue: Select this option to run the sequence of post-functions on the current issue. This is the default option.

• Sub-tasks of the current issue: Select this option to run the sequence of post-functions on the sub-tasks of the current issue

• Parent issue of the current sub-task: Select this option to run the sequence of post-functions on the parent of the current issue

• Issues that belong to the current issue (Epic): Select this option to run the sequence of post-functions on the issues that belong to the current Epic

• Epic of the current issue: Select this option to run the sequence of post-functions on the Epic of the current issue

• Child issues of the current issue in the Portfolio hierarchy: Select this option to run the sequence of post-functions on the child issues of the current issue in the Portfolio hierarchy

• Parent issue of the current issue in the Portfolio hierarchy: Select this option to run the sequence of post-functions on the parent issue of the current issue in the Portfolio hierarchy

• Issues linked to the current issue through any link type: Select this option to run the sequence of post-functions on all issues linked to the current issue

• Issues linked to the current issue through the following link type: Select this option to run the sequence of post-functions on the linked issues of a specific link type. Select the specific link type under “Issue link”

• Issues returned by the following Nunjucks template: Select this option to run the sequence of post-functions on issues returned by the result of a Nunjucks template. Input a Nunjucks template which is a comma-separated list of valid issue keys. For example:

  • "TEST-1"

  • "TEST-1","TEST-2"

  • {{ targetIssue.fields.parent.key }}

  • {{ targetIssue.fields.subtasks | join(",", "key") }}

• Issues returned by a JQL search:  Select this option to run the sequence of post-functions on issues returned by a JQL search. Input a JQL search expression. For example:

  • project = TEST returns issues of the project with the key TEST

  • project = {{ targetIssue.fields.project.key }} and assignee = {{currentUser._accountId}} returns issues of a project that belong to the project with key TEST and the assignee is the current user

  • Code Block
    {% if targetIssue.fields.assignee %} assignee = {{targetIssue.fields.assignee._accountId}} {% else %} issuekey=INVALID-1 {% endif %}

    Note that the {% if %} block is necessary to avoid an invalid JQL query when the issue is unassigned. In that case, the template will return a valid JQL query that returns no issue (issuekey=INVALID-1).

Passing variables within a sequence

Using the {% setContextVar %} Nunjucks tag you can pass data from one post-function to a subsequent post-function.

transition.context: Holds all the context variables added in the current post-function. For example, if you create a context variable myVar in the first post-function of the sequence:

{% setContextVar myVar = "a value" %}

This variable will then be available to subsequent post-functions as:

{{ transition.context.myVar }}

 Note that this variable will not be available in the Nunjucks tester. 

Variables specific to the Create Issue post-function

newIssueKey: Stores the issue key of the last issue created by a Create Issue(s) post-function in the sequence. You can access it as:

{{ transition.context.newIssueKey }} 

newIssueKeys: Stores an array of the keys of all the issues created by any Create Issue(s) post-function in the sequence. You can access the created issues from

{{ transition.context.newIssueKeys }}

For example: to add a comment on the current issue with the keys of the issue created

Issues created are:
{{ transition.context.newIssueKeys | join(",") }}

You can access the information of a specific issue using the issue filter. For example: To get the assignee of the issue created by the Create issue post-function:

{{ transition.context.newIssueKey | issue("assignee") | field("fields.assignee.displayName") }}

Error handling

If one of the post-functions fails with an error, the remaining post-functions in the sequence are run anyway. To stop the execution of subsequent post-functions after an error occurs, select the option “Skip subsequent post-functions if a post-function encounters an error”.

Conditional execution

To execute this post-function based on the result of a Nunjucks template see Conditional execution.

Delayed execution

Use case

A typical use of this workflow post-function is to run a list of post-functions in sequence considering the asynchronous nature of post-functions. Consider a use case where you want to clone an issue and its subtasks to another project, then:

1. Add the "Sequence of post-functions" post-function to the transition

2. Select the “Target issues” as “Current issue”

3. In the sequence add the "Create issue" post-function.

   1. Select the destination project in "Project"

   2. Select the "Issue type" as "Calculated" and input: 

      Code Block
      {{ issue.fields.issuetype.name }}

   3. Select the "Link to new issue" as "clones"

   4. Configure the fields

   5. Click on Save

4. Add another "Create issue" post-function to clone the sub-tasks

   1. Select the destination project in "Project"

   2. Select the "Issue type" as "Subtask"

   3. Under the "Parent issue" input the following template:

      Code Block
      language js
      {{ transition.context.newIssueKey }}

   4. Select "Multiple issue creation" option and input the following template:

      Code Block
      language js
      {{ issue | subtasks | length }}

   5. Save the post-function.

5. Click on "Save"

6. Publish the workflow.

Error handling

If one of the post-functions fails with an error, the remaining post-functions in the sequence are run anyway. To stop the execution of subsequent post-functions after an error occurs, select the option “Skip subsequent post-functions if a post-function encounters an error”.
