Why am I getting this error page?

Question

Hi All,
On my application I have a form that I use to add new Users of the system. On the Users table User Id is the primary key & it's the first item on the form. Also, on this form I have a password field (among other fields) which is read only & it's initially set to Password1 for new users by clicking on the Set button next to the Password field. behind this button there's a page process: Process Point: OnSubmit - After Computations And Validations that does this: BEGIN
:P2_PASSWORD := 'Password1';
END;When I enter a new user, the folllowing happens;
1. When I specify User Id first & then click the Set button the page redirects to an error page & displays:
ORA-01403: no data found
Unable to fetch row.2. When I click the Set button first - the password field is set to default password & regardless of the order in which I fill in other fields, I get to create a new user.
3. When I fill in all other fields first (including setting password to Password1 after I have filled in these other fields before) & I make sure that I fill in the User Id field last - the application does not crash - a new user is created.
I have even changed Process Point to:
OnSubmit - Before Computations And Validations
Before Header
After Header& the page process sequence to the lowest on list - but does not make a any difference! How come I'm getting that error? Thank you for your time.

Hi Kamo,
I noticed following things in you page:-
1. You have Fetch Row from USERS which is fired on page load when USER_ID field is not null.
Now, when you enter all the data and click on set button , your page loads and USER_ID field this time is not blank.. so ur page run Fetch Row from USERS process which tries to get data from table for USER_ID enter in that field. since this user id does not exist you get the error message.
I Modified you code...
instead of a page process , I have create two dummy button which calls javascript and set that field.. I have entered the javascript in page header..
You will see two botton both the buttons are actually hyperlins.. and does same function... so you can delete one of them.. you can delete your set password process also..
