Groovy Script doesn't work JIRA 7

[Sam Morris]

Since upgrading to JIRA 7 my script on Scriptrunner to update a check box is no longer working.

The script finds the checkbox with it's existing values and adds a new value. 

def checkbox_cf = customFieldManager.getCustomFieldObjects(parent).find {it.name == 'BI Deployed to Environment'}
def new_value = ComponentAccessor.optionsManager.getOptions(fieldConfig)?.find { it.toString() == 'UAT' }
def current_options = parent.getCustomFieldValue(checkbox_cf);

checkbox_cf.updateValue(null,parent,new
 ModifiedValue(parent.getCustomFieldValue(checkbox_cf), 
current_options + [new_value]),changeHolder);

The error is occurring on 

current_options + [uat_value]

Can anyone help?

Thanks guys the answers is - 

def customFieldManager = ComponentAccessor.getCustomFieldManager()

Try

def customFieldManager = ComponentAccessor.customFieldManager

or

def customFieldManager = ComponentAccessor.getCustomFieldManager()

I believe the customFieldManager must be gotten by a function instead

def customFieldManager = ComponentManager.getInstance().getCustomFieldManager()

I declare the customfieldManager like this - 
 

def MutableIssue parent = (MutableIssue) issue.getParentObject();

ComponentManager componentManager = ComponentManager.getInstance();
def customFieldManager = ComponentAccessor.CustomFieldManager
def optionsManager = ComponentManager.getComponentInstanceOfType(OptionsManager.class)
def changeHolder = new DefaultIssueChangeHolder();

I'm getting this error in the logs -

groovy.lang.MissingPropertyException: No such property: CustomFieldManager for class: com.atlassian.jira.component.ComponentAccessor
Possible solutions: customFieldManager

Hi Sam,

              Did you turn on debugging and check what log file says ?
