Live update
Object fields can become “Live”, meaning their display value updates each time the issue is viewed.
To activate this “Live” feature, use the “Recalculate displayed value on issue view” option.

When Live mode is enabled:
The display value refreshes on issue view
The refresh mechanism relies on a dedicated query: “Live Path” for REST API data sources, or “SQL Live Query” (for database connections)
Why Use a Separate Live Path?
A Live Path is useful when:
Optimizing calls to the data source
Example:
Path retrieves all work items
Live Path retrieves only the selected item
Avoiding $userinput problems
User inputs cannot be reused in Live Paths.
Instead, Live Paths should rely on the stored ID.
Filtering by the current field value
You can reference the stored ID using:
${currentCustomfield.id}for Single Select${currentCustomfield.ids}for Multi Select
(Or $currentCustomfield.id if FreeMarker is disabled.)
Example – Jira API
Initial path:
/search/jql?jql=project=MYPROJECT&fields=*all
Live path:
Single select:
/search/jql?jql=key=${currentCustomfield.id}
Multi select:
/search/jql?jql=key in (${currentCustomfield.ids})
In these examples, Freemarker is activated.
If Freemarker is not activated replace ${currentCustomfield.id} by $currentCustomfield.id
Known limitations
The “Live” update takes into account the cache, which means that it can take some time to reflect data source changes in the connected custom field, depending on what you’ve configured in your datasource & field.
For Live fields, the value is only updated when the issue is viewed, nowhere else, which can lead to discrepancies on reports or JQL filters.
