Set assignee from component lead using script listener

[Alvin]

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

Hello @Drishti Maharaj ,

I just tried your script. It is working fine, I only had to add this line at the end to update the issue : 

ComponentAccessor.getIssueManager().updateIssue(ComponentAccessor.getUserManager().getUserByKey('user_key'), issue, EventDispatchOption.DO_NOT_DISPATCH, false);

Of course you will need to map all the priorities in your switch but that does not seem to be the issue.

Let me know if that helped.

Hi @Antoine Berry , thank you for taking the time to reply, if I add the additional script from you, the following error occurs:

Hi @Antoine Berry , I managed to figure out what was wrong :)

Just needed this at the top:

import com.atlassian.jira.issue.IssueManager
import com.atlassian.jira.event.type.EventDispatchOption

and it worked perfectly! 

Thank you so much!
