Summary

If you need to validate a transition based on the existence or non-existence of one or more issues determined from a JQL query, then read on! It is very simple to do with a Conditioned validator.

Steps

Step	Discussion	Examples
Create a JQL query that will determine if the transition can proceed or not.	Test the JQL in the Issue Navigator first.	No unresolved sub-tasks: parent = XXX-1 and resolution is empty
Add a Conditioned validator to the appropriate workflow transition	Assumes you have installed the Update on Transition for Jira add-on
Put the JQL query in the JQL Query field	It is likely you need to use one or more substitution variables like %original_key% in place of a specific values you may have used while testing	parent = %original_key% and resolution is empty
Condition by how many issues are found by the query	%jql_result_count% is the more substitution variable that says how many issues were found Put that value in the Condition 1 Value field Put 0 in the Condition 1 Regex field Likely user cases are: Proceed with the transition if there are 0 issues found - do not select the Negative checkbox Proceed with the transition only if there was at least 1 issue found - select the Negative checkbox	All sub-tasks must be resolved `Condtion 1: Value: %jql_result_count% Regex: 0`
Add a user friendly message that will show if the validator fails	Add appropriate text to the Message field and optionally use substitution variables.	`Message: All sub-tasks must be resolved before you can proceed. The following sub-tasks are not resolved: %jql_result_list%.`
Save the post function
Run a test scenario	Use Retrieve problem determination information to debug your scenario if necessary. JQL errors will be logged in the JIRA application log. Note: This is the most common cause for problems. Remember, the JQL query runs under the user's permission unless you are using Acting user support.
