Page Identifiers
Each ADM page is identified by a unique, non-negative integer. Page 0 (zero) exists by default; you must create and assign numbers to all other pages that you need.
You need not assign page numbers sequentially, and it is fine to leave gaps. You can define up to 32767 pages for a given context—a much larger number than you would probably want to try to manage. To create a new page, you need merely make it the current Design Page (see the "Special Pages" section).
A page remains in existence as long as it is the current Design Page, or has objects assigned to it. AppBuilder automatically destroys empty pages that are not current.
