Set assignee from component lead using script listener

Alvin_junjul

Hello Community, I need help on scriptrunner, I need to set assignee based on the component's lead. Below is the code that I'm using

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.customfields.option.LazyLoadedOption

// a map with select list option to Component
def componentsMap = [
"BOSS" : "Component1",
"Mashery" : "Component2",
]

def issue = event.issue as MutableIssue

def selectList = ComponentAccessor.customFieldManager.getCustomFieldObjectByName("Affected Service")
def selectListValue = issue.getCustomFieldValue(selectList) as LazyLoadedOption

// there is no value for the select list - therefore do nothing
if (! selectListValue) {
return
}

def componentManager = ComponentAccessor.projectComponentManager
def componentName = componentsMap.get(selectListValue.value)
def component = componentManager.findByComponentName(issue.projectObject.id, componentName)
def userManager = ComponentAccessor.userManager
def components = issue.componentObjects.toList()

if (component) {
componentManager.updateIssueProjectComponents(issue, [component])
}
issue.setAssignee(ComponentAccessor.userManager.getUserByKey(component.lead))

In this code, I have Affected Service as a single select list, if BOSS has been selected, the Component Field will update and set to Component1, but the assignee remains unassigned even if I have default assignee on my component. I know that there's something wrong with my code because I'm a beginner. I need to change assignee everytime component field is changed, that's why I used script listener. Thanks

Hi Alvin

Assigning an issue with a script is more complex. Jira needs to check whether the assignment is valid. Therefore you have to use th issueService.

Replace your issue.setAssignee line with:

def issueService = ComponentAccessor.getIssueService()
def user = component.componentLead
def currentUser = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
def assignmentValidation = issueService.validateAssign(currentUser, issue.id, user.key)
if (assignmentValidation.isValid()){
    issueService.assign(user, assignmentValidation)
} else {
    log.debug(assignmentValidation) // you probably have to loop through the ErrorCollection object
}

At the top of the script you can import loggers and set the level. It can be useful to have some logging when troubleshooting:

import org.apache.log4j.Logger
import org.apache.log4j.Level
  
def log = Logger.getLogger("com.yourjira.componentupdate")
log.setLevel(Level.DEBUG)

and this is the whole code , already applied your suggestions

That error means the component is null.

On your issue: do you selected a value for Affected Service?

And does Component1 and Component2 exist in your project?

It's probably safer if you put the assignment part in your if:

log.debug(component)
if (component) {
    componentManager.updateIssueProjectComponents(issue, [component])
    def issueService = ComponentAccessor.getIssueService()
    def user = component.componentLead
    def currentUser = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
    def assignmentValidation = issueService.validateAssign(currentUser, issue.id, user.key)
    if (assignmentValidation.isValid()){
        issueService.assign(user, assignmentValidation)
    } else {
        log.debug(assignmentValidation) // you probably have to loop through the ErrorCollection object
    }
}

I also added log.debug(component)

You can check the execution log after updating your Affected Service field to check whether the component was found.

Hi @Charlie Misonne , I just want to ask something. How can I add Group , from Single Group picker field, based on the value of the Affected Service Field.

Scenario right now is whenever requestor selects "BOSS" as value of Affected Service Field, Component Field will be updated and Assignee will be the Component Lead.

Now I want to add Group too, based on the Value of Affected Service Field inside the condition. Can you help me? Thank you!
