Update a checkbox on a parent issue based on subtask value

[Sam Morris]

Hi,

I was wondering if anyone can help, using script runner I need to update a checkbox on a parent issue based on a value in a subtask. The script will be executed when the subtask is transitioned into a closed state.

I'm trying to write a custom script.

I've written the following so far -

import com.atlassian.jira.ComponentManager;
import com.atlassian.jira.issue.MutableIssue;
import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.customfields.manager.OptionsManager;
import com.atlassian.jira.issue.fields.config.FieldConfig;
import com.atlassian.jira.issue.ModifiedValue;
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder;



MutableIssue parent = issue.getParentObject();
ComponentManager componentManager = ComponentManager.getInstance();
def customFieldManager = componentManager.getCustomFieldManager();
def optionsManager = ComponentManager.getComponentInstanceOfType(OptionsManager.class)

def cf = customFieldManager.getCustomFieldObjects(parent).find {it.name == "New Environment"}
def fieldConfig = cf.getRelevantConfig(parent);
def uat_value = ComponentAccessor.optionsManager.getOptions(fieldConfig)?.find { it.toString() == 'UAT' }

def changeHolder = new DefaultIssueChangeHolder();
def modVal = new ModifiedValue(parent.getCustomFieldValue(cf),uat_value.toString());

cf.updateValue(null,parent,modVal,changeHolder);

----------------------------------------

I get the following error -

java.lang.ClassCastException: com.atlassian.jira.issue.customfields.option.LazyLoadedOption cannot be cast to java.util.Collection
