Page Zero
Page Zero acts as a template page for the application. All components of Page Zero will be rendered on all the pages in the application. Compared to a normal page, it consists of only the page rendering part. The following components can be used on Page Zero:
Computations
Branches
Regions, for example, forms, reports, lists, and HTML
Items
Dynamic actions
In combination with the use of conditions for the components that determine on which specific pages the components will be rendered, is a flexible place for reusable components. Think, for example, of a menu made up of a list region, centralized help functionality, personal information, task list, and so on.
Page Zero has no processing part. The pages themselves—where the components of Page Zero will be rendered when running the application—will take care of this.
