scriptrunner validator issue

[Alexander Verzakov]

Hi.

I add simple validator, that need to check amount of attachments.

import com.atlassian.jira.component.ComponentAccessor
def cfm = ComponentAccessor.getCustomFieldManager()
try
{
      def result = issue.getCustomFieldValue(cfm.getCustomFieldObject('customfield_10200')).value; 
if(result.equals('Аварийная'))
{
      log.error("заявка аварийная");
      return true
}
else
{
     if(issue.getAttachments().size()>=1)
     {
       log.error("заявка не аварийная, есть вложение. Заявка: " + issue.getKey());
       return true
      }
     else
     {
          log.error("заявка не аварийная, нет вложений. Заявка: " + issue.getKey());
          return false
     }
}
}
catch(Exception e)
{
      log.error("не получено значение поля Тип заявки");
      return false
}

It is correctly defines the situation but successfully execute transition even validator need to return false.
What i am doing wrong?

I think that this is a workaround?

To disallow the transition you set invalidInputException to an instance of a new InvalidInputException.
Yep it's work's, but i not sure that "Workflow error" is proper solution.
