I'm trying to create a custom field based on custom fields of all child issues connected.

Tristan_Willis

I keep getting the error: ERROR [runner.ScriptFieldPreviewRunner]: Script field preview failed for field that has not yet been created

java.lang.NumberFormatException: For input string: "null"

 

My code is below.. Sorry very new to this so feel free to point out all my mistakes.

 

 

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.component.pico.ComponentManager
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.CustomFieldManager

def issueLinkManager = ComponentAccessor.getIssueLinkManager()
def componentManager = ComponentManager.getInstance()
def customFieldManager = ComponentAccessor.getCustomFieldManager()

def url = ComponentAccessor.getApplicationProperties().getString("jira.baseurl")
def estimateRollup = 0
issueLinkManager.getOutwardLinks(issue.id)?.each
{
outLink->
def firstLevelChildIssue = outLink.destinationObject
def customField = customFieldManager.getCustomFieldObjectByName("Cumulative Epic Estimation in Numbers")
def estimateRoll = issue.getCustomFieldValue(customField)
def estimateRollString = estimateRoll.toString()
def estimateRollInt = Integer.parseInt(estimateRollString)

if(outLink.getIssueLinkType().getName().equals("Parent-Child Link"))
{
estimateRollup += estimateRollInt
}

}

return estimateRollup

My guess is that you have set the output template to be a string, but you are returning a number.

There are some errors in your loop as well.  I would

• Move the def customField line to before the loop, you don't need to fetch the field every time (just the contents)
• Change the issue.getCustomFieldValue to read the issue at the end of the link, not the current issue
• Look at the field type of "Cumulative Epic Estimation in numbers" - is it really a string?  Also, you'll want to catch empty values and not process them further.
