A system receives an action override rule and stores it, including display criteria associated with a user interface page, into a hierarchy of rules for displaying multiple user interface pages. The system determines whether the action override rule in the hierarchy of rules matches request criteria associated with a user action, in response to receiving the user action. The system displays the user interface page associated with the display criteria if the action override rule in the hierarchy of rules matches the request criteria associated with the user action. If the action override rule in the hierarchy of rules does not match the request criteria associated with the user action, then the system can identify a hierarchical rule that is a hierarchical match for the request criteria associated with the user action; and display a user interface page associated with the hierarchical rule that is the hierarchical match.
