In your application both page 2 and page 4 branches to page 5. Page 5 has a Cancel button
which currently redirects to page 2, however it should redirect to either page 2 or page 4
depending on the originating page. Which three actions need to be performed?
A.
Create two application items: LAST_PAGE and CURRENT_PAGE.
B.
Create an application computation on item LAST_PAGE, computation point Before
Header, type PL/SQL Function Body and the computation body as: BEGIN :LAST_PAGE :=
nvl(:CURKENT_PAGE, :APP_PAGE_ID. ; :CURRENT_PAGE := ;APP_PAGE_ID; RETURN
:LAST_PAGE; END;
C.
Create an application computation on Item LAST_PAGE, computation point After Submit,
type PL/SQL Function Body and the computation body as: BEGIN :LAST_PAGE :=
:CURRENT_PAGE; :CURRENT_PAGE : = :APP_PAGE_ID; RETURN :LAST_PAGE; END;
D.
On page 5 create a validation to check whether the value stored in application item
LAST_PAGE is equal to the value of APP_PREVJ_PAGE_ID where APPJ>REV_PAGE_ID
is Built-in Substitution String in Oracle APEX that stores the number of calling page.
E.
On page 5 use the value stored in application item LAST_PAGE to go back to the page
