NEW QUESTION 16
Which two statements are true when navigating on a Page Definition window?
Answer: AD
Explanation:
A: The Referenced Components page lists page components and shared components associated with the current page.
Note: A list of values (LOV) is a static or dynamic definition used to display a specific type of page item, such as a radio group, check box, popup list, or select list. LOVs can be static (that is, based on a set of predefined display and return values) or dynamic (based on SQL queries that select values from tables). Once created, an LOV can then be referenced by one or more page items.
You define LOVs at the application level by running the LOV Wizard and adding them to the List of Values repository.
D: The History page displays a history of recent changes to the currently selected page by developer (or user), application, page number, modification date, component, and
action.
