Scripted Field generates Cannot invoke method getCustomFieldValue() on null object

AndreH

Hello,

I have 2 separate Scripted Fields on a Sub-task. These fields are reading existing data from a custom field on the parent issue.

Field 1 on Sub-task (Parent Prod Start Date). This field reads a custom date field from the parent issue and displays it on the sub-task.

Field 2 on Sub-Tasks (Parent DBA Estimate). This field reads a custom numeric field from the parent issue and displays it on the sub-task.

Both of these scripted fields is generating errors in the logs during a re-indexing and also when a user is working on a parent issue.

error - javax.script.ScriptException: java.lang.NullPointerException: Cannot invoke method getCustomFieldValue() on null object. A stacktrace has been logged.

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

Here is the code for Parent Prod Start Date -

import com.atlassian.jira.issue.Issue;

import com.atlassian.jira.ComponentManager;

import com.atlassian.jira.issue.CustomFieldManager;

import com.atlassian.jira.issue.fields.CustomField;

import com.atlassian.jira.component.ComponentAccessor;

def field = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Prod Install Start Date/Time")

def abc456 = issue.parentObject.getCustomFieldValue(field);

return abc456;

Here is the code for Parent DBA Estimate -

import com.atlassian.jira.issue.Issue;

import com.atlassian.jira.ComponentManager;

import com.atlassian.jira.issue.CustomFieldManager;

import com.atlassian.jira.issue.fields.CustomField;

import com.atlassian.jira.component.ComponentAccessor;

def field = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("DBA Estimate")

def abc123 = issue.parentObject.getCustomFieldValue(field);

return abc123;

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

Here is the complete error -

Nic is correct as usual, but I don't think that's the problem.

I did a quick test and it seems like jira requests the value of the custom field even when it's not in the context. I don't know why... I think there is a reported bug for this in jamieechlin.atlassian.net/browse/GRV but it's not fixed, because I'm not sure what I can do. I need to reproduce and report to Atlassian.

In the meantime I would do:

if (issue.isSubTask()) {
...
return something
}
return null

This can happen when either

The field you are trying to read has no data
The field you are trying to read is not valid for that project/issuetype

In both cases, wrapping the "getCustomFieldObject" call in "if field not null" type if blocks should fix it.

Hi Nic,

I am not able to get the logic correct for checking against the "if field not null". Do you have an example of the syntax?

Thanks

Argh, sorry, I've made a mistake

Most of your code is actually ok, and, for the record, this is what I do to avoid empty field errors:

CustomField budgetField = customFieldManager.getCustomFieldObjectByName(budgetFieldName);

def thisPaidCR = issue.getCustomFieldValue(paidDaysField)
  if ( thisPaidCR )
    { 
    total += thisPaidCR
    }

But although that will catch the error I thought you're getting, I have looked in the wrong place.

You have:

issue.parentObject.getCustomFieldValue(field);

The problem is not "getCustomFieldValue", it's "parentObject". That is returning a null.

AndreH

Yes, it is on the parent object where the null error is coming.

i tried to verify there is a valid field on the parent, however it is still generating the same issue.

Here is the new code, that still doesn't work

def field = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Prod Install Start Date/Time")

def abc456 = issue.parentObject.getCustomFieldValue(field);

def total = "Hello";

if (abc456 != null)

{

total = (abc456)

}

return total;
