How do I redirect to a page via a button but also populate a field on page2

Question

I am trying to redirect to a second page via a button but at the same time populate a item on the second page from a function that returns a sequence.
I tried all sort of methods, adding page processing, adding dynamic actions, adding branching and cannot get this to work.
The button must create a new record on the second page, but populate unique key at the same time. Because redirecting does not Submit, adding page processing AFTER submit does not work. I get that, but the following also will not work and I don' know why
Create dummy field on page 1
Create page processing that populates the field via PL/SQL "On Submit"
Create Region button that simply Submits page
Create branch that on submit redirects to second page and moves the value from the dummy field on first page to the field on the seocnd page.
I am new to Application Express and love trying to figure issues out myself but am at a loss with something that should be so simple. Any help would be appreciated.

Hi,
As i understand from your requirement,
I am trying to redirect to a second page via a button but at the same time populate a item on the second page from a function that returns a sequence.You want to goto page 2 from page one on click of a button, and when loading the page two you want to populate the item on page two with a sequence number.
if that is the case, try using Button,
Action: Redirect to page in this application
then on page two, create a page process,
Process Point:*On load before header*
Source >> Process >>
begin
select seq_name.nextval into :P2_ITEM from dual;
end;this should do your requirement.
