For information on where the post-function needs to be placed on a transition, see Placing post-functions on a transition.

When you set add this post-function on to a transition and trigger the transition on an issue, the add-on checks for the default member of the selected Project Role. If such user member is found, it assigns the issue to the fetched user. If not, the issue is assigned to a random member of the selected Project Role. If there are multiple default members, a random member is picked and the issue is assigned to the picked user.

If you want a specific user to be picked, you must either use the User Property trick (explained below) or use a more specific Role (one that contains only a single user).

Since JIRA does not support the notion of a default member for project roles, the Assign to role member function identifies the default member of a project role by going through all the members of the project role looking for a User Property with the following two characteristics:

• Property key: defaultAssignee
• Property value: contains a comma-separated list of entries in the form ProjectKey -> *RoleName. *For example:  

For backward compatibility, the following two forms are also supported:

• Property Key: {ProjectName}x{RoleName} (for example: CoolProjectxQAMembers)
• Property value: "default" (without the quotes)

Or: (since 1.5.3)

• Property Key: defaultAssignee{n}  (where n is a number from 1 up, for example: defaultAssignee1)
• Property value: {ProjectName}x{RoleName} (for example: CoolProjectxQAMembers)
