scriptrunner when creating subtask using customfield

[Chax]

hi, I am using select list(cascading) type custom field to trigger the script below. I only want it to validate the first field value. I only want Mpower - MOBILE and Mpower - WEB as my trigger, but when I included 2nd value, it is not creating subtask. 

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.ComponentManager
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.fields.CustomField
import org.apache.log4j.Logger
import org.apache.log4j.Level

def cf_name = customFieldManager.getCustomFieldObjectByName('Product (New)') as String
def x = issue.getCustomFieldValue(com.atlassian.jira.component.ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Product (New)")) as String
if(
x in ["[null:Mpower - WEB, 1:PowerForm - 3.3.3]",
"[null:Mpower - WEB, 1:PowerForm - 3.3.2]",
"[null:Mpower - MOBILE, 1:WorkForce - 1.10.17]",
"[null:Mpower - WEB]",
"[null:Mpower - MOBILE]"] && issue.getSubTaskObjects().size()==0)
{
return x
}

 the 2nd field is the version, and there are atleast 35 of it. if I included it on the the script, and there's a new release, I will need to update it.

any work around?

Hi Chax, 

How are you using this script? For example, are you using it in Behaviour, a Post Function, etc?
