'Checkout' ui action does not appear.
Jakarta and forward.
Article versioning enabled.
Failing out of box condition on ui action.
The 'Checkout' ui action is calling KBVersioning().canCheckout(current) in the condition which is checking for a previous version of the article not in 'published','outdated'. KB0014320 (previous version) is set to 'Retired'. This returns a record to the function setting canCheckout to false, therefore the condition is not passing. Setting this to 'outdated' will resolve the behavior.
There are other examples of records not displaying the ui action, none of these articles appear to have previous versions. This is also why the ui action is failing here, because we are failing KBVersioning().canCheckout(current) again in the ui action.
