Post-function script to set Assignee based on custom drop-down selection

[laurahbantug]

Hello,

I am using Script Runner (LOVE this add-on!) to create a post-function script to set Assignee based on a custom field drop-down selection.  I am using the below script but can't seem to get it to work.  Any ideas on what I am missing here?  I am a bit of a novice when it comes to scripting.  Thanks!

import com.atlassian.jira.ComponentManager
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.comments.CommentManager
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.util.ImportUtils
import com.atlassian.jira.user.util.UserManager
import com.atlassian.crowd.embedded.api.User
import com.atlassian.jira.component.ComponentAccessor
  
MutableIssue issue = issue
ComponentManager componentManager = ComponentManager.getInstance()
CustomFieldManager customFieldManager = componentManager.getCustomFieldManager()
CustomField customFieldX = customFieldManager.getCustomFieldObject("customfield_10022")
def xFieldVal = issue.getCustomFieldValue(customFieldX)
if(xFieldVal == "Client Operations" ){
   User userA=ComponentManager.getInstance().getUserUtil().getUser('lbantug')   
   issue.setAssignee(userA);
   }
issue.store()

this works ...

import com.atlassian.jira.ComponentManager
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.comments.CommentManager
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.util.ImportUtils
import com.atlassian.jira.user.util.UserManager
import com.atlassian.crowd.embedded.api.User
import com.atlassian.jira.component.ComponentAccessor

userManager = (UserManager) ComponentAccessor.getUserManager()
MutableIssue issue = issue

CustomFieldManager customFieldManager = ComponentManager.getInstance().getCustomFieldManager();
CustomField customField_name = customFieldManager.getCustomFieldObjectByName( "LeadComponent" );
def comp = issue.getCustomFieldValue(customField_name);

def str = comp.toString().toLowerCase();
def userToReassign = issue.getAssignee()

switch ( str ) {
case "XY" :
userToReassign = userManager.getUser('AB');
break
case "YX" :
userToReassign = userManager.getUser('BA');
[...]

break

default :
userToReassign = userManager.getUser('CD');
}

issue.setAssignee(userToReassign);
issue.store();
