How would you validate if Priority is set to "P0"

[Hani Juha]

Use Case: When a bug is filed as a Priority 0 or "P0", I want to trigger a validation rule that requires the user to enter information into a field ("Why is this a P0?")

Is this possible?

Hi @Hani Juha,

One solution is the following script if you have Script Runner add-on.

• Go to the Bug Workflow and Edit
• Find "Create transition"
• Add Validator-> Script Validator -> Custom Script

Paste the code;

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.fields.CustomField
import com.opensymphony.workflow.InvalidInputException

CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager();
CustomField reasonFieldCF = customFieldManager.getCustomFieldObject("customfield_xxxxx");

if(issue.getPriority().getName().equals("P0")){
    if(issue.getCustomFieldValue(reasonFieldCF) == null){
            invalidInputException = new InvalidInputException("Please fill the reason field.")
    }
}

Also, you can do it via Behaviours feature. There are many examples on the web.
