Example: Require at least one "duplicates" issue link when resolution = "Duplicate"
When we resolve an issue setting Resolution as "Duplicate", we would like to enforce the existence of at least one linked issue with issue link type "duplicates".
We use Boolean Validator with math, date-time or text-string terms with the following configuration:
Text to be parsed is: %{00028} != "Duplicate" OR count(linkedIssues("duplicates")) > 0
Once configured, transition "Resolve Issue" will look like this:
Alternative expression
Since version 2.1.22, logical connective IMPLIES is available. Using it, an equivalent expression can be written like this:
%{00028} = "Duplicate" IMPLIES count(linkedIssues("duplicates")) > 0
Other examples of that function
- Block a transition until all sub-tasks have certains fields populated
- Block an epic's transition depending on linked issues status and due date
- Block or hide a transition for an issue depending on its issue links
- Block or unblock a transition after an issue rested a specific time in a status
- Block transition until all sub-tasks are in a specific status category
- Close parent issue when all sub-tasks are closed
- Enforce a field (Select List) to be set when another field (Radio Button) has a certain value (works with any kind of field type)
- Ensure that all issues linked with a certain issue link type have "Due Date" field set
- If field A is populated then, field B must also be populated
- Limit issue creation per role and issue type
- Limit the number of hours a user can log per day
- Limit valid dates for work logs
- Make "Time Spent" field required when there is no time logged in the issue

- Make attachment mandatory depending on the value of certain custom field
- Make different fields mandatory depending on the value of a Select List custom field
- Make linked issues, sub-tasks and JQL selected issues progress through its workflows
- Make parent issue progress through its workflow
- Prevent issue creation if another issue with same field value already exists
- Reject duplicated file names in attachments
- Require at least one sub-task in status "Resolved" or "Closed" when "Testing required" is selected in Check-Box custom field
- Require issue link when resolving as duplicate
- Restrict parent issue from closing if it has sub-tasks that were created during a given parent issue status
- Restrict sub-task type creation depending on parent issue status
- Restrict sub-task type creation depending on parent issue type
- Set a condition in a global transition which only applies in a certain status
- Validate a custom field "Story Points" has been given a value in Fibonacci sequence
- Validate compatible values selection among dependent custom fields
- Validate only issue links created in transition screen
- Validate that multi-user picker custom field A does not contain any user in multi-user picker custom field B
- Validation and condition based on time expressions
