[Kiranped]

Below is my code using in behaviour script- not working

Requirement: Auto-set Assignee based on cascade field select

import com.atlassian.jira.component.ComponentAccessor

def formhddmo = getFieldByName("cascadefield")
def assigneeField = getFieldById("assignee")
def formassign = getFieldByName("assignee")

//log.debug("----------------> " + formhddmo.getValue())
//log.debug("----------------> " + formhddimos.getValue())

String userName="kiran.p@xxx.com";

List<String> listString = formhddmo.getValue() as List<String>

def parentValue = listString.get(0)

switch(parentValue){
case "Dfgd ACC ART": userName = "jay.asdfsd@xxx.com";break;
case "HDdfgdD Infrastructure ART": userName = "Bryan.asdfsd@xxx.com";break;
case "Dfgsdf Command Flow ART": userName = "Pawan.asfasd@xxx.com";break;
case "Power and Performance": userName = "ajhsdg.Begum@xxx.com";break;
case "FWsdgdTest & Val": userName = "Alexander.Peladtt@xxx.com";break;
case "Sdfgsdfg Fmwre":
switch(formhddimos.getValue()){

Hi @Kiranped 
Have you tried the username instead of the email. 

For example, assuming  "jay.asdfsd@xxx.com" email is "jay" username.
case "Dfgd ACC ART": userName = "jay";break;

[Kiranped]

email and username are the same

[Gustavo Félix]

Ok. 
Do you have this import in your code?

import static com.atlassian.jira.issue.IssueFieldConstants.ASSIGNEE

@Gustavo Félix 

Thanks for the reply.

Yes, I have.

My Jira version is 8.5.3, it's strange to even the below snippet not working

def assigneeField = getFieldById("assignee")

String userName="kiran.p@xxx.com"

assigneeField.setFormValue(userName)

This exact code works for me:

import com.atlassian.jira.componentAccessor
import static com.atlassian.jira.issue.IssueFieldConstants.ASSIGNEE

def username = "XXXX";
getFieldById(ASSIGNEE).setFormValue(username)

Can you try it with your username ?
