Override a UI action for an extended table without an Action Name - Known Error

Override a UI action for an extended table without an Action Name Description If a UI Action does not have an Action Name, it is not possible to override it for an extended table.

Steps to Reproduce

1- Login as administrator 2- Create a UI Action for Task table (you can use the existing 'Assign to me' UI Action, just enable Form Link to test the issue easier) 3- Override the UI Action for Incident table by following the steps: https://docs.servicenow.com/csh?topicname=t_OverrideOrRmvAUIActionForExtTbl.html&version=latest (Name: Assign to me, Active: true, Form Link: true, List context menu: true, Show insert/update: true, Script: current.incident_state = 4; current.update();) 4- Go to any Incident record, click 'Assign to me'

Notice that the UI Action still points to the one created for Task table (If you've enabled Form Link, right click to the UI Action and click 'Edit UI Action', you will be redirected to Task's UI Action)

Even adding the Task's UI Action to 'Overrides' field doesn't change the behaviour.

Workaround This is expected behaviour. As a workaround apply one of the following:

Add a same 'Action Name' to both of the UI Actions or

Enter a lower 'Order' number for the extended table's UI Action
