created a Form type page ( here i will create more regions ) which will show user data after login, like a user profile and it can be editable, also add/update profile picture.
i tried to add a process before header to assign value as :P24_ID := :SESSION_USER_ID (after successful login, SESSION_USER_ID have user's ID column value for later use), when run this page apex showing error page here it says: ora_sqlerrm: ORA-06502: PL/SQL: numeric or value error
i set default value for P24_ID, type: Item and Item=SESSION_USER_ID then nothing appear in Form.
how i can have the login user's value and allow update only.
regards
