I want a custom field ( Single user picker) to pick a user from project role and update

[Raj Kumar]

Hi,

I want a custom field ( Single user picker) to pick a user from the project role and update but if the user in project role and reporter are the same it should clear the custom field and update with a default value. Please help in achieving it.

The below code only updates the field but does not clear the field if the project role user and the reporter are the same.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.ModifiedValue
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
import com.atlassian.jira.issue.util.IssueChangeHolder
import com.atlassian.jira.bc.issue.IssueService
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.user.ApplicationUser
import com.atlassian.jira.component.pico.ComponentManager
import com.atlassian.jira.project.Project
import com.atlassian.jira.project.ProjectManager
import com.atlassian.jira.security.roles.ProjectRole
import com.atlassian.jira.security.roles.ProjectRoleActors
import com.atlassian.jira.security.roles.ProjectRoleManager

def groupManager = ComponentAccessor.groupManager

def issue = issue as Issue

def user = ComponentAccessor.jiraAuthenticationContext.loggedInUser

def customFieldManager = ComponentAccessor.getCustomFieldManager()
def issueService = ComponentAccessor.getComponent(IssueService)
def issueInputParameters = issueService.newIssueInputParameters()

ComponentManager componentManager = ComponentManager.getInstance()
//ProjectManager projectManager = componentManager.getProjectManager()
ProjectRoleManager projectRoleManager = ComponentManager.getComponentInstanceOfType(ProjectRoleManager.class) as ProjectRoleManager
IssueChangeHolder changeHolder = new DefaultIssueChangeHolder();

// name of role here
ProjectRole controllerRole = projectRoleManager.getProjectRole("Controller")
ProjectRoleActors controller = projectRoleManager.getProjectRoleActors(controllerRole, issue.projectObject)
def controllerField = customFieldManager.getCustomFieldObjectByName("Controller")
def actor = controller.getApplicationUsers()
actor.remove(issue.reporter)

controllerField.updateValue(null, issue, new ModifiedValue(issue.getCustomFieldValue(controllerField), actor), changeHolder)
