Items not in session state when column link used and prevpage not submitted

Question

I have a report on page 2 (cemetery lot info) with a column link to page 3 (burial info).
There is a process on page 3 that updates billing information using items from page 2, and billing code selected on page 3. The problem is, if the user does not submit page 2, session state is null, or has values from previously submitted page 2. How do I make sure the billing info is correctly updated from items displayed on page 2, if they are not in session state?
begin
if :P3_BILLING_CODE = 'OWN' then
:P3_BILLING_NAME := :P2_OWNER1_FIRSTNAME||' '||:P2_OWNER1_LASTNAME;
:P3_BILLING_ADDRESS1 := :P2_OWNER_ADDRESS1;
:P3_BILLING_ADDRESS2 := :P2_OWNER_ADDRESS2;
:P3_BILLING_CITY := :P2_OWNER_CITY;
:P3_BILLING_STATE := :P2_OWNER_STATE;
:P3_BILLING_ZIP := :P2_OWNER_ZIP;
:P3_BILLING_PHONE := :P2_OWNER_PHONE_AC||'-'||:P2_OWNER_PHONE_EX||'-'||:P2_OWNER_PHONE_SC;
elsif :P3_BILLING_CODE = 'MGR' then
:P3_BILLING_NAME := :P2_NEW_MANAGER;
:P3_BILLING_ADDRESS1 := :P2_NEW_MANAGER_STREET;
:P3_BILLING_ADDRESS2 := null;
:P3_BILLING_CITY := :P2_NEW_MANAGER_CITY;
:P3_BILLING_STATE := :P2_NEW_MANAGER_STATE;
:P3_BILLING_ZIP := :P2_NEW_MANAGER_ZIP;
:P3_BILLING_PHONE := :P2_MANAGER_PHONE_AC||'-'||:P2_MANAGER_PHONE_EX||'-'||:P2_MANAGER_PHONE_SC;
elsif :P3_BILLING_CODE = 'FH' then
:P3_BILLING_NAME := :P3_FUNERAL_HOME1;
:P3_BILLING_ADDRESS1 := :P3_FUNERAL_HOME_ADDRESS;
:P3_BILLING_CITY := :P3_FUNERAL_HOME_CITY;
:P3_BILLING_STATE := :P3_FUNERAL_HOME_STATE;
:P3_BILLING_ZIP := :P3_FUNERAL_HOME_ZIP;
:P3_BILLING_PHONE := :P3_FUNERAL_HOME_TELEPHONE;
end if;
update cm_burial set billing_name=:P3_BILLING_NAME, billing_address1=:P3_BILLING_ADDRESS1, billing_address2=:P3_BILLING_ADDRESS2, billing_city=:P3_BILLING_CITY, billing_state=:P3_BILLING_STATE, billing_zip=:P3_BILLING_ZIP, billing_phone=:P3_BILLING_PHONE
where recordid=:P3_RECORDID;
end;

Hello,
If I understand you correctly, it seems like your page logic is a bit problematic. The scenario I see is that the user is populating the form part, submiting the page, and the report region is being displayed (as the where clause depends on an item from the form region). Now, the situation you are describing, where the billing information is not correct, is possible if the user changed some of the form items on page 2, didn't submit the page – hence didn't update the report region – but still chose to branch to the next page, using the (non-updated) report link column. If I understand it correctly, you should first correct this situation. If the user is changing some details in the form section, the page should be re-submitted. This will resolve your problem, because as part of the page submit process, session state will be set correctly.
I believe this is the simplest and correct solution. Other options, like updating session state per changed item (using JavaScript) will be much more complicated.
