Placing post-functions in a transition

JMWE shows an error message on the issue view if any error occurs during the execution of the post-function. This message is displayed only if the current user is a Jira administrator.

When you add this post-function to a transition and trigger the transition, the add-on copies the value(s) of the selected From field to the To field of the current issue.

Options

Return "parent-child" for cascading custom fields: This option is applicable for the Select list (cascading) custom fields. If you select the Return "parent-child" for cascading custom fields option, values from both the parent and child lists are copied into the destination field. For example, a custom cascading field has the values A and 1 in the parent and its child lists respectively. When this field is copied into a text field
- without the option, the value 1 is copied into the text field
- with the option, the value A - 1 is copied into the text field.

Copy only if not set: Copies the value(s) of the From field to the To field of the current issue, only when the To field is empty on the current issue.

Create missing value(s): Allows creating any missing Component/s or Version/s while setting or copying a field that expects Versions or Components. Note this is applicable for version and component fields.

Ignore empty value: Will not set (clear) the destination field of the current issue, if the value of the source field is empty or null.

Add value(s) to the destination field: Appends the value(s) of the selected From field to the To field of the current issue. This is applicable only to multi-valued fields.

Send notifications: Jira sends notifications for the change in the selected To field value on the current issue. You can control the default value of the "Send notifications" option in the Configuration page under JMWE administration. Click here for more information.

Conditional execution

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

Run As

Run as current user: The current user will be the author of the field change.

Run as add-on user: The add-on user will be the author of the field change.

Run as this user: Any user selected in this field will be the author of the field change.

Running this post-function as any user other than the "Add-on user" is discouraged

If you select any option other than "Run as add-on user", so that the change appears to be done by the current user or a specific user, the following must be true:

The destination field must be present on the Edit screen applicable to the issue being modified
The selected user must have the Edit issues permission on the issue being modified

Delayed execution

Post functions are provided with an option to delay their execution. You need to select the number of seconds to wait until the post-function is run, a default of 1 sec to a maximum of 20 seconds.

Workflows that depend on post functions being executed in a specific order fail due to the asynchronous nature of the Connect post-functions in Jira Cloud. One of the workarounds is to delay the execution of the post-functions and thereby create a more predictable execution order. For example, on the approval of a Story you want to create sub-tasks and immediately transition them; in this case, you will have to delay the execution of the Transition Linked Issues post-function, so that the sub-tasks are created before they are transitioned. See the use case below.

It is recommended to use the Sequence of post-functions post-function or Shared Action post-function post-function to run a list of post-functions in a sequence instead of applying a delay.

Sample use cases for Delayed execution

On the creation of a Bug, assign it to a member of the QA team and then add the Assignee to the Watchers.

Steps

Create a QA project role, with the testers as its members.
Add the Assign to role member post-function to the transition Create of the Bug workflow.
Select QA as the project role to look for.

Add the Copy value from field to field post-function to the Create transition of the Bug workflow.
Select Assignee as the From field.
Select Watchers as the To field.
Select the Delayed execution option and select 5 sec from the Delay drop-down.

On the approval of a Story, create subtasks for Development and QA, and transition them to In Progress status.

Steps

Add the Create issue post-function to the Approve transition of the Story workflow.
Select Same as current issue from the Project field.
Select Subtask from the Issue type field.
Select Current issue from the Parent issue field.
Repeat the above steps for the Development subtask.

Add the Transition linked issues post-function to the Approve transition of the Story workflow.
Select Issue Link Type as is Parent of.
Select the Delayed execution option and select 10 sec from the Delay drop-down.

Use case

A typical use case for this post-function is to copy a field to another field value of the same issue during a transition. Consider a use case where you want to set the components of an issue with a value selected from a cascading field that carries the Main and Sub-components in parent and child. To configure this:

Add the Copy value from field to field post-function to the Create transition of the issue workflow.
Select the Cascading field as the From field.
Select the Components field as the To field.
Select Return "parent - child" for cascading custom fields option.

Note: The Component name should be in Component - Subcomponent format.
