removing the value from custom field or set to null

[Hentsu]

I want to remove the value from the custom field or set it to null. The code below is not working as expected. Please advise me.

Thanks in advance.
regards

import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.fields.CustomField;
import com.atlassian.jira.issue.CustomFieldManager;

def customFieldManager = ComponentAccessor.getCustomFieldManager();
def customField = customFieldManager.getCustomFieldObject("customfield_10107");
def value = issue.getCustomFieldValue(customField);

customFieldManager.removeCustomField(customField)

Hi

Try 

import com.atlassian.jira.event.type.EventDispatchOption
import com.atlassian.jira.component.ComponentAccessor
def user = ComponentAccessor.jiraAuthenticationContext.loggedInUser
def customFieldManager = ComponentAccessor.customFieldManager
def issueManager = ComponentAccessor.issueManager
def customField = customFieldManager.getCustomFieldObject("customfield_10107")
def value = issue.getCustomFieldValue(customField) //<-- don't know why you wanted this
issue.setCustomFieldvalue(customField, null)
issueManager.updateIssue(user, issue, EventDispatchOption.DO_NOT_DISPATCH, false)

Hi Peter,

Thanks for the advice. I have tried with code below, but it still doesn't set the custom field value to null.

Please advise.

import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.fields.CustomField;
import com.atlassian.jira.issue.Issue;
import com.atlassian.jira.issue.MutableIssue;
import com.atlassian.jira.event.type.EventDispatchOption;
import com.atlassian.jira.issue.context.IssueContextImpl;
import com.atlassian.jira.issue.fields.config.FieldConfig;
import com.atlassian.jira.config.PriorityManager

def customFieldManager = ComponentAccessor.customFieldManager
def userManager = ComponentAccessor.getUserManager()
def issueManager = ComponentAccessor.issueManager
def user = userManager.getUserByName("UserA")
def value = issue.getCustomFieldValue(customField) 

MutableIssue mutableIssue = (MutableIssue) mutableIssue.setCustomFieldValue(customField,null)
issueManager.updateIssue(user, mutableIssue, EventDispatchOption.DO_NOT_DISPATCH, false)

Perhaps some more detail as to where this code is implemented exactly.

This code seems incomplete.

For example:

• where is "customField" defined from the line "def value = issue.getCustomFieldValue(customField)"
• What are you expecting "MutableIssue mutableIssue = (MutableIssue)" to do? There is no data to put into the mutableIssue variable

Sorry for the response delay. I have a plan to implement in the post function(Transition stage)

I tried to research and modify the script but no luck. it still is getting an error as below,

 1. If function doesn't work

 2. cannot set the custom value to null

Thanks,

Ah! 

Took me a minute.

Simple typo. It should  be setCustomFieldValue not setCustomerFieldvalue
