How to configure a column which lists all the users who have a role in the containing project

Introduction 

The default activity list, lists all the users that can access JIRA. If you want to restrict this list to the users who have a specific role in the JIRA project, you will have to do some SQL plumbing

Solution

The column specification is as follows

col.responsible = Responsible col.responsible.type = list col.responsible.query.ds = jira # # The query is using project:key to select the users from the projectroleactor table # who have a role in the project # Only lists explicit configured users. # col.responsible.query.parameters = project:key col.responsible.query = SELECT cu.display_name, cu.id \ from cwd_user cu \ inner join projectroleactor pa on cu.user_name = pa.roletypeparameter and pa.roletype = 'atlassian-user-role-actor' \ inner join project pr on pa.pid = pr.id \ where pr.pkey = {0}


The *project:key* is one of the issue values that can be used to construct a query.  The resulting grid looks as follows (the drop down is listing only the members which are
currently working on this project)
