Error on scripted field (illegal "as" cast)


I have this script that returns an error in JIRA log and is referred to in Scriptrunner support (

Can anyone direct me to the fix needed in this script?




import com.atlassian.jira.component.ComponentAccessor

import com.atlassian.jira.issue.fields.FieldManager

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

import com.atlassian.core.util.DateUtils


def fieldManager = ComponentAccessor.getCustomFieldManager() as FieldManager

def startCF = fieldManager.getCustomField("Downtime Start") as CustomField

def endCF = fieldManager.getCustomField("Downtime End") as CustomField

def startTime = startCF.getValue(issue) as Date

def endTime = endCF.getValue(issue) as Date

if (startTime == null || endTime==null) {return null}


return (endTime-startTime) / (60 * 1000) as Double

Try removing all the "as" statements.  You don't need them, as groovy handles the object types automatically.

Er, fieldManager doesn't have getCustomField as a function like that.


def myCustomField = com.atlassian.jira.component.ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("My Field")

There is an improvement, Thanks

can you look at the next issue?

Those two values are dates, not numbers.  As humans, we can make the intuitive leap from "Sunday - Wednesday = 3 days", but computers can't.  You might as well be asking it to do "apple - cat = ???".  Convert the dates to epoch time or something like that (epoch time is something like "number of milliseconds since base date")

The same code doesn't produce any type checking errors for me - what version of the plugin are you using?
