subtasks fields need to block parent transition

Scott Federman_r83gv8

using scriptrunner, could someone share with me how i would create a validator where i have three custom fields in a subtask (unit price, quote number, part number) that must be filled out in order to transition the parent? And if not will return a message that says " unit price, quote number, part number on each line item must be entered to proceed"

This should do the trick

import com.atlassian.jira.issue.Issue;
import com.atlassian.jira.component.ComponentAccessor;
import com.opensymphony.workflow.InvalidInputException;

def customFieldManager = ComponentAccessor.getCustomFieldManager();
def unit_price = customFieldManager.getCustomFieldObjectByName('Unit Price');
def quote_number = customFieldManager.getCustomFieldObjectByName('Quote number');
def part_number = customFieldManager.getCustomFieldObjectByName('Part Number');

def subTasks = issue.getSubTaskObjects();
if(subTasks) {
subTasks = (Collection<Issue>)subTasks;
for(Issue subTask : subTasks) {
 if(!(subTask.getCustomFieldValue(unit_price) && subTask.getCustomFieldValue(quote_number) && subTask.getCustomFieldValue(part_number))) {
 throw new InvalidInputException("Unit price, part number, and quote number are required on subtasks")
 }
}
}
