How to get the checked values in a custom field and apply them to a text field (on the same ticket)?

[James Fishwick]

Here is some starter code where I try to get the checked values in a custom field and apply them to a text field (on the same ticket). But no joy yet. Some superfluous junk in here, I know.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.event.issue.IssueEvent
import com.atlassian.jira.bc.issue.IssueService
import com.atlassian.jira.event.type.EventDispatchOption
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.IssueInputParameters
import com.atlassian.jira.project.Project
import groovy.transform.Field
import com.atlassian.jira.issue.customfields.option.LazyLoadedOption
import com.atlassian.jira.config.SubTaskManager
import com.atlassian.jira.user.ApplicationUser
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.issue.ModifiedValue
import com.atlassian.jira.issue.customfields.manager.OptionsManager
import com.atlassian.jira.issue.customfields.option.*
import com.atlassian.jira.ComponentManager
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
     
def cfManager = ComponentAccessor.getCustomFieldManager()
def componentManager = ComponentManager.instance
def optionsManager = ComponentManager.getComponentInstanceOfType(OptionsManager.class)
def customFieldManager = ComponentAccessor.getCustomFieldManager()
  
//Get parent issue
Issue issue = (Issue) event.issue;
//Check, that it is a subtask type issue
if(!issue.isSubTask())
    return
  
MutableIssue parentIssue = issue.getParentObject();
Set issueLabels = parentIssue.getLabels();
def customField = customFieldManager.getCustomFieldObject("customfield_27132")
def selectedValues = customField.getValue(issue)*.value
def target = customFieldManager.getCustomFieldObject("customfield_27736")
String labels = selectedValues.join(',')
//CustomField cf = cfManager.getCustomFieldObject(condField)
//Options options = cf.getOptions(null, cf.getRelevantConfig(issue), null);
 
//def cfTarget = cfManager.getCustomFieldObject(target)
//issue.setCustomFieldValue(target, selectedValues.join(","))
//issue.setCustomFieldValue(target, "test")
target.updateValue(null, issue, new ModifiedValue(target, labels), new DefaultIssueChangeHolder());

Main issue for cusotm fields is to know type of returned value.

Whant type is for custom field you get information from?

[James Fishwick]

It is a multiple checkbox field... 

[Vasiliy Zverev]

This type of field returns List<Option> since you need a loop to get all values. Here is code example to get all selected options as single string:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.customfields.option.Option
import com.atlassian.jira.issue.fields.CustomField

CustomField customField = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("fieldName")

StringBuilder stringBuilder = new StringBuilder()
 ((List<Option>) issue.getCustomFieldValue(customField)).each {
     stringBuilder.append(it.getValue()).append(", ")
 }

return stringBuilder.toString()
