Problem with item of type DB column, reinitialized in a process

Question

Hello,
I have a problem with an item P216_username with source type=database column(empty in this case). In a process On Load-After Header(with a sequence number bigger then the Fetch Row sequence number) , I change the value of this item:
:P216_USERNAME := 'custom_value';
When I run the page, I see the item P216_USERNAME with the value from the database column(empty), instead of attributed value from the process('custom_value').
Here is a copy of the page in a debug mode:
0.00: Session: Fetch session header information
0.00: ...Metadata: Fetch page attributes for application 107, page 216

Hi,
Tomáš : I noticed that if i change the Source Used to 'Only when current value in session state is null' it works but I dont think its a normal behaviour.
Scott: Thanks, it's working now with the post computation callculation attribute.
Thanx for answers,
