Set assignee based on a former assignee

Use case

Store the last assignee in a status in a hidden User Picker field and update the Assignee field with it in a posterior transition.

This use case requires the implementation of two Update or copy field values post functions in two different transitions.

Prerequisites

Set up a custom field

Create a User Picker (single user) custom field and name it Last Assignee In Status

Restrict its context to the desired projects.

Do not add it to any screen! It will be used internally.

Configuration

Add the Update or copy field values post function to the transition or transitions that leave the status in question.

Target issue

Choose Current issue

Field

Choose Last Assignee In Status

Value

Choose Set field value manually

Expression

Use the following expression with the expression editor in Advanced text mode.

hasChanged(%{issue.assignee}) = true ? previousValue(%{issue.assignee}) : %{issue.assignee}

Add the Update or copy field values post function to a posterior transition.

Target issue

Choose Current issue

Field

Select Assignee

Value

Choose Copy field value from current issue and select the field Last Assignee In Status

Conditional execution

Restrict the usage of the post function with the following conditional execution. Replace the field code with the appropriate one for the field Last Assignee In Status before using it.

%{issue.cfaaaaa} != ""
