Increment a numeric custom field post function

[Jonathan Down]

Hi I'd like to increment a custom field when certain transitions take place. The default value is 0 and should count upwards by 1 each time a post function is run. I've searched around and found a few different answers but when I put any of them into the Code box all the import statements show "unable to resolve X".

Does anyone have a scriptrunner script I can use? Thanks!

Hello,

Could you provide the script which is not working?

[Jonathan Down]

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

Long customFieldId = 10065;
DefaultIssueChangeHolder changeHolder = new DefaultIssueChangeHolder();
CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager();
CustomField cf = customFieldManager.getCustomFieldObjectByName(customFieldId);

Double currValue = (Double)cf.getValue(issue);
Double newValue = currValue+1;

cf.updateValue(null, issue, new ModifiedValue(currValue,newValue), changeHolder);

I found it here:

https://community.atlassian.com/t5/Jira-questions/How-can-I-increment-a-custom-field-value-in-a-post-function/qaq-p/74690

When I paste that into the code box all the import statements show an X and can't resolve Name.

Change the script to this one and replace customFieldName with the name of your custom field

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


DefaultIssueChangeHolder changeHolder = new DefaultIssueChangeHolder();
CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager();
CustomField cf = customFieldManager.getCustomFieldObjectByName("customFieldName");

Double currValue = (Double)cf.getValue(issue);
Double newValue = currValue+1;

cf.updateValue(null, issue, new ModifiedValue(currValue,newValue), changeHolder);

How do I define "customFieldName"? The page I linked says to use a Long but your response suggests a String. If the field has ID 10065 and is named "CR Ready" what should the parameter value be?

[Alexey Matveev]

You define it "CR Ready"

Hello, I'm a beginner with the scripts and I want to do the same thing as Jonathan but for how many times an issue has been reopened. So I entered this script in the Reopen transition and I created a numeric custom field with a default value of 0.

Each time I test it with a new request, I get this error : 

java.lang.NullPointerException: Cannot invoke method getValue() on null object

I'm pretty sure it's really easy to fix but everything is new to me so... :|

What should I do?

Thanks!
